Project Farm just did a comparison of carbide burrs. If you’re looking for quality burrs, bits, etc. it’s difficult to find much better than Cle-Line. Quality cutting tools for decades. Made in USA.

When I was in my High School auto shop, I pulled the heads on my 1971 Pontiac. One of the instructors said, “Say what you want about Pontiac, but they have fully machined combustion chambers.” And they did.

You're exactly the shop teacher I needed, back then

Mopar Al has been a great addition, definitely a hard worker!

port and polish, thanks man. I avoided the mistake of cheap burrs and bought quality. I watch your shows, not once, but several times. love the straight forward no bull teaching, thank you. Elmer

RIP Jim Bennett 🙏 Love to Tony, Kathy and all of both crews!

My late father, owned two 1970 roadrunners. Both had 383 magnums and 727 torque flight transmissions. One wouldn’t pull your hat off your head. The other, was the fastest car he ever owned.

UT: "in these there's a lot of weirdnesses". That's the story of my life...

I finally realized something Uncle Tony. Watching this channel is like reading the old Hot Rod magazines. I loved those magazines, and I learned a lot from them. I am learning a great deal more, however from your channel. Thank you for bringing those magazines to life.

I made a speed controller from a ceiling fan/light dimmer . It makes the tootsie roll sanders last longer on the die grinder.

Tony from one Italian to another, Cannoli port! I love it!

Always learning something from every video

porting cylinder heads is actually really fun especially if there aluminum cuz you can use sanding rolls instead of big ass hogging burrs and really fine tune every port without having to worry so much about going to crazy with reshaping!

I watch a lot of KZfaq...... This is by far the coolest build (Slag Hammer) and the one I am anticipating the most!!!!!! also.... I get SO many comments on my Uncle Tony's "This is sketchy even by my standards" T shirt every time I wear it!!!!!!

I did a gasket match and bowls and blending like you are Tony. On my 440 i built for my 74 Runner. What a difference. It seriously woke up that motor!

another incredible informative video. thank you!

I remember doing this on the 3.5 v6 in my intrepid some time back, took it from being an sorta ok pulling car, to slamming you back like it was a v8. It’s amazing what a little zen time with a die grinder, heads, and intake can do.

I live vicariously through tony

Thank-you Uncle Tony for taking the time to teach, encourage and mostly inspire all of those who are thinking about doing engine work of any sort, especially the extra bits to be done if you want to take your motor to the next level without breaking the bank.

Reminds me of a set of factory Pontiac 455 heads I had. Never even thought of doing a port job before I got them. When I got these heads it literally looked like they were cast in volcanic cinder. Lots of slag and uneven surfaces. Took them to a mechanic to have them smoothed out. Guy said he got carried away and did what he called a stage 2 port job. Major difference between before and after.

I am learning. I love your videos. I just play with little engines but the theory is the same.

slag hammer is looking awesome

On my 596 smog heads I found that the short side of the bowl transitioning to the runners was more of a 90 degree turn then a nice round corner. I know most guys highly recommend that you never touch that side as its really easy to ruin your heads here, but just removing that lip and rounding that corner had a pretty big impact on my flow bench.

Thank you I was having that same thing with my 1973 w-100 318 I’m going to check it out Tomorrow Saturday I ordered new Edelbrock heads for it now I got it look closer when I take it apart thank you

The ridge next to the valve seat inside the bowl will give you about 15 cfm more, face cutting the exhaust valve will yield about 7 cfm @ .050. Use a sanding roll to get the rest of the port smoothly transitioned.

Thank you so much for these videos Tony and crew.!! You have taught me so much in such a short period of time. Thanks again Brutha👊

Awesome video, mopar al did a great job on that cage, can’t wait to see the car fly down the track! I’m also loving the solo dolo style of video, gets better every time.

I had a 318i bought from a junk yard I went to change the intake and as I was looking down the intake ports on it I found flashing in no4 intake port it took up over 1/3 of the port. Good thing I went to change that intake .yes I ported it out .

I’m building an AMC 360 . Those heads were very well designed but there is always room for improvement. I did some port detailing on these . I don’t have the engine back together yet but I have great expectations !

I remember those dang aggravating sharp edges inside of heads and intakes before myself, and I would always grind them out because when I would be visually checking them by feeling around looking for cracks and such they would cut my finger due to being razor sharp and also didn't want them to breaking off and getting into the cylnders and eating up the piston tops, rings, or cylnder walls. Also I was taught to always be thinking of the next guy that would be working on them which was sometimes me but not always. I've also seen that casting slag inside the head ports like you mentioned and they were everywhere you looked back then. I hated those things because of the time required to get rid of them. Another AWESOME video Uncle Tony.

When I port my Studebaker heads I'll follow your methods! Building a 259 V8 with an R2 Avanti cam and headers. Thanks!

Tony, You will need to produce more than one book.

I'm sure a lot of people have heard it Mopar stands for mama's old pig aint running. it reminds me when I was a kid. my grandma had 4 door may be duster but like seventies police cruiser Model .with A 440 She was like 75 years old and went to visit my dad tuned it up and We went for a ride. My dad punched it over this bridge. that thing burned tire over the entire bridge and it was awesome. Pop said maybe grandma shouldn't have this car.

Awesome video. I'm in the process of building a hotrod. A lot of these videos have been very helpful in this. Thanks Tony! Don't stop the great content!

Nice informative video, I’ve seen a lot of guys ruin heads by doing too much grinding on heads and not know when to stop.

I love the old school tech and advice! My dad taught me much in the same manner. Shade tree mechanics 101! I learned quite a few tricks that you've mentioned and some that I've never heard anybody else mention but they work!

Every industry seems to have quality control issues like these from time to time. High production quotas, workers taking their jobs for granted and only showing up for a pay check. Great info on this subject.

I am surprised that you didn't mention anything about cleaning up oil drain holes/slots...

Budget horsepower upgrades using inexpensive tools and common sense that anyone can do. OUTSTANDING!

The Mopar Cylinder Head Monk... @∅

They used to have a process called extrude honing which was a nice way of cleaning the bowls up

As always TONY very enlightening and worth every second.

Something that could make the channel better: a contrasting pointing tool; red or green or whatnot.

Great video. Spot on with the explanation of manufacturing. On point with explaning castings.

It is amazing what can be done with stock castings and some work!

I once drank about 50 gallons of beer over several weeks after work “detailing” some ford 351 Windsor heads. Well it was actually quite extensive surgery. People would about shit themselves when they saw a 302 turn over 9k rpm with ford cast iron heads. It was standing an all steel and glass maverik on its ass for almost the entire first gear in the adapted power glide tranny. More fun than a sack of monkeys. ;)

Loving your practical performance tips. Always learning something from your vids :)

When making "Rate" was incentivised with additional wages/pay for foundry/factory workers is possibly a reason for slight inconsistencies. This was a very common practice with industries here in Michigan and other rust belt state's.

Your knowledge is priceless thank you absolutely love watching

Fantastic video U.T.....! ! keep'm coming....! Simple improvments that will/could net large gains...! excelent job explaning the basics ....! Thank u...!

Excellent info once more Uncle Tony. Cheers & stay safe😊

Rebuilt a 440 in the late 90's shit you not i pulled 1.3 lbs of casting sand out of the block. Absolutely blew me away, have not sen anything like that before or since

Sorry to hear about Jim, i was following his channel and will miss his updates, he did a very good job explaining and he cared about his work...

Awesome video! Great info! And man you already nailed this filming by yourself thing, thanks tony!

Yes Sir. I've helped my brother work on the double hump 461 heads. SBC, But he LOVED, Mopar! Just never got around to afford one his self.

Had a 69 Pontiac Ventura 10.5 compression. The thing never ran good until I started feeding it 100 low lead av gas. It was very carboned up and choked up. And real good until a guy thought it would be a good idea to shift at 6500 it w with a long rod Pontiac 400

Awesome video! I consider that just plain good engine building techniques. A good cleanup to fix the manufacturing mistakes.

You sir are an absolute legend! Thanks so much for sharing your knowledge 👍🏻

Great Video !

Been doing that for 50+yrs.When some guys say ported and polished when they see it,I say more like clean-up on aisle 5

Uncle Tony giving us more bits of horsepower. Thanx UTG!!

Great information Tony thank you

I always like the video before I ever even start watching Uncle Tony. 🙏❤️

Hey Tony, Tim here, another GREAT, informative, and accurate vid.......just remember to NOT fool with the exhaust valve angles, and such....NO REVERSION please......but, i've experienced ur exact thing on ur 318 cuda....certain castings have junk in the way, creating a hot spot, igniting our mixture b4 we're ready, causing ping, etc...... had it on a set of Poncho heads (casting #48).......large valve, off a RAIII 400....yep, same issue, we did what you suggested (but it was 35 yrs ago)......and the motor responded SUPER!!!.......great stuff my brother!!

Spark knock!! I had that same issue a long time ago on a 318 ( used car). I tried everything I could to get rid of it, timing, rebuilt the carb etc. Nothing worked until the day I decided to try some "Super" gas. Problem went away and never heard a knock afterwards. Thanks for all the videos. Regards - Mike

Great info, learned a little something too. Over hang on a combustion chamber can act as a glow plug. Thanks UT ✌️

I made it early, very rare for me. But I know this will be legit good stuff because you speak truth. Good vid! (I haven't seen it yet but I know it's gold)

I had too much to think this morning, and it occurred to me something marvelous has occurred [if the wizards of the tech world don't screw it up with cancel culture]. Where the printing press brought us a beautiful means for ideas, modern video [like YT] brings a place for passing on things about doing. It's not locked down in distribution rackets like movies were. And a lot of things are gobbledygook to most - until you show them. Then the lightbulb goes off, confidence is boosted, and we all win for it. Tony is a doer: things make sense with his hands. It used to be difficult to share that knowledge - it was the stuff of apprenticeships or goodwill of close friends. As I observe my work over the years and the people I worked with, there's more learning in doing than anything else. Thanks, man.

Great content thank you!

Good video. I did some porting on my Ford truck 302 EFI intake manifold, just almost gasket matching, mild stuff and smoothing out the bad kinks. Doing that sure beats buying an aftermarket manifold in my case.

Very well explained. A person can put all good stuff in their engine and bolt on some crap heads and it will run like crap. Heads are one of the best investments a person can make in a engine. For the home mechanic on a budget you explained the best power gainer a person can do. Remove and match a little. This is where less is more power. We want air flow...not room to park a vw in the Port. Well explained Tony. Great video.

Excellent talk

Thanks , waiting for the next one.

My first port job was a 4.1 ford falcon inline 6. IT could keep up with a 302 v8 ford motor. there is magic in porting. I ported my Royal Enfield bullet. I recon it could do most the race bikes in it's class now. It is just removing the little bits that are made in casting that does not work.

Tony, I reworked a set of 906 heads about 20 years ago, you should mention the short turn of the intake, there's power there as I'm sure you know, after the heads were done they flowed 267 on adverage, I spent hours on those heads, with them stock and a 30* back cut, car ran 10.9-11.00, after the port work, I picked up 2-3 tenths and 3-4 MPH.

Use hearing protection when grinding if you don't want to have constant ringing / damage in later life. !!!

Great video Tony

thanks Tone

Nice!!! God Bless! 😎

That roll bar looks slick! I cannot wait to see this one do some passes!! As far as cylinder heads go. I don't trust myself to do more then just clean up the casting marks. To many expensive things can go wrong.

Now this is something I need to learn Tony. I have a pair of Pontiac 13 heads that are waiting for me to port. My car is a 1976 Firebird that originally came with a Pontiac 350 2bbl and had a cracked block so my friend had a 400 out of a junk 75 grand prix that was rusted and locked up. The engine shop managed to rebuild the block and get all the rust off and its been 18 years and still running good. Its a near stock rebuild with unported 6X4 heads, SUM-2800 cam stock q jet intake and stock log exhaust manifolds. Lots of torque with okay midrange. The block is a late model 500557 thin wall so I'm leaving it alone I read they don't do well with a lot of power mods. I found a better 400 block from a 1969 grand prix that can take the pressure better. I tore the engine completely down to the bare block and brought it to the engine shop. They reconditioned it really nice. Its ready for all new components I would like to get a forged lighted balanced rotating assembly from Butler. I don't want to stroke it to 461 unless I use bigger chamber heads. The smallest stroker kit is 4" I like it to be a little bit rev happy and not like the 4.5". I bought a pair of reproduction ram air three exhaust manifolds. I will let the cylinder heads decide what cam it wants after I pocket port them. I don't like high stall converters for the street they only work up to 35mph anyway but they are necessary for the dragstrip and they make a car drink gas 100 times worse. Acceleration from 40 to 75 is more fun on the highway. I think a little cam change goes a long way and going from a SUM-2800 to a SUM-2801 can be more change than I imagine. Maybe SUM-2802 might be too much? I'm not trying to outrun a hellcat I know that will never happen in that car. Not with Ram Air three exhaust that will be the pinch. I don't know what cam would work best with those manifolds. I just want to see what I can make it do. I still have to get swirl polished undercut valves. I don't know if a new damper and flexplate comes with the rotating assembly. What a mess. I have read about building a homemade flowbench and I have a collection of old vacuum cleaners. I'm 60 and planning my retirement hahahaha 😆

I gasket matched and detailed a pair of heads for a Ford Ranger V6 one time, it was astonishing how much flashing was blocking the airflow coming across the bowl. Just cleaning up the heads made a huge difference in how the vehicle ran.

Good on ya uncle Tony slaghammer looks bloody good The red roll cage makes the car look like a bloody redback spider…..!! This car is proof to my mind that all passenger domestic production cars should have a tilt front end….!!!! All the best from Melbourne Australia

Great stuff

My dad talks about his fabled 68 Roadrunner 383 stick he bought while in the Corps. Says it was the fastest bone stock car he ever owned. Only was beaten once drag racing, and that was against a worked 427 Chevelle by a fender. However, he had the engine apart once and everything appeared bone stock. Not even an aftermarket cam. Maybe he benefitted from a freakishly great set of those inconsistent heads.

Very helpful information. Interesting to find out how “off” a set of factory heads can be. Time to get out the die grinder!

I never called it "detailing", but yes, a very appropriate term for this. The most dramatic I ever noticed was when I replaced head gaskets on a Scout II, with a 304. I thought, well I have it apart, I will make it better. Port (gasket) matching intake and exhaust on the heads as well as the intake, and exhaust manifolds, and some clean up of the ugly stuff. . . I don't recall if the head gaskets were exactly the same thickneess as the old, but when i got it running again .. . Wow! It pulled so much stronger! And it sounded so much better too . .

Thank you for the great video Uncle Teacher, school is in session.

Love the content

I've done the head porting and polishing stuff in my kitchen on the kitchen table which is heavy, big and doubles as a work bench. 10 hours sounds about right to me. A couple hours a night for a week is what I remember spending last time I did it. That may have included new valve seals, springs etc. IF anything, at the very least port match the gaskets, intake side as well, and smoothing the crap out of the bowls. If you don't want to spend 10 hours, do that at least. I did it with a Hobo fright kit with an air grinder and a dremel, variety of grinders and sand paper rolls.

man I went crazy on my 360 magnum heads. Took out a lot of metal, smoothed everything, made it all swoopy and curvy, and I sharpened the holes that the valves go though. By the way I did this on cracked heads. Had the seats and valves machined by a good shop. Now here is where it gets weird. I made a mistake and somehow two of the head bolts didn't tighten down on number one cylinder. But those things ran really good when the engine was cold it still had compression and the power was very noticeable. Not hard to do go for it, if you are more careful than me you will make more power and have fun.

Still have my mopar performance big block bowl porting plates I bought back in the 90's

Back in the late 70's I built a slant 6 for a 63 Dart GT. The ports on that head were horrid. Had fins all over, looked like the sand cores had cracked. Cleaned all that up, made a world of difference.

I did thanks. the way of the gear head, head porter!!!

Late 70s and 80s and 90s Ford 460 heads have a large lump sticking down it the top of the exhaust port that is drilled for the air pump injection. If you find a pair with these lumps and they are not drilled, you can grind the lump out and gain a bunch of horse power. And the same heads have large cast areas for the guides that can be cut down to help intake flow.

Planning on getting a 460 ford from an rv soon, definitely gonna port the heads while goin through it, might as well 🤷🏽‍♂️

Long ago I bought a set of 906 heads off a 2 barrel 383, I don’t know if mine were representative of them all, but I was stunned when I pulled them apart, it looked as if they had used the wrong cutters under the valves. The throats were so small the big valves were of no benefit. I saw the same situation on a set of 67 HP 440 heads, under the bigger exhaust valves, the throat was the same as the standard LP head.

Uncle Tony,as i've said before,i really appreciate how you encourage the home mechanic/hotrodder to "go for it,without being condecending.There's too much of that out there. Maybe you could do a vid on cc'ing combustion chambers.I just got through with porting a set of the 452 big block Mopar smog heads. I kept all the shavings each day until it literally became a compulsion (but boy was it worth it ! Torque out the A$$.

4:58 "Weirdnesses"? I like it!

I've had some 350 Buick heads with all kinds of bad casting mismatching inside, besides having too long of an intake port, the previous era heads for the 300 and 340 V8 were miles ahead on combustion chamber, port, and manifold design. For a street/strip engine I leave the intake manifold ports smaller than the head intake ports, reduces reversion...
