The battle to make clean, usable power is won or lost at the cylinder heads. Here's a simple how-to that anyone can follow and duplicate at home using nothing but basic tools and a little bit of time.

This is not so much a port, but prep and quality control for a casting that received minimal basic machining, then kicked out the door by the car company that made it. Call this a good cleanup that anyone can do, and if you want to hand it over to a porter, he can concentrate on what moves flowbench numbers. The large wall of casting flash in that bowl is beyond sad: they really didn't give a rip. If that broke loose, it's enough to destroy an otherwise good engine. It makes me think if I went back to the 60s/70s in a time machine [to place a few key rides in the family to enjoy later], the first thing I would do on every car is yank the heads off, and fix the sloppy work just like this vid shows. Could be fun, watching the dealer go slack jawed as I demand heads pulled on a brand new car before it leaves the lot...and I would not budge: no sale without my inspection/cleanup.

*>>>* One other tip I'd give - especially for beginners - is to start with the port areas first to get a feel for how much material the carbide bit removes with every pass you make, and how it "feels" as the bit cuts away material. You really want to get a feel for it before doing the more intricate areas of the bowls. You're learning, so if you make any minor mistakes, the ports are a good place to learn because they are more forgiving of any minor mistakes you may make. Get a feel for how your bit cuts and feels with the ports first before doing the bowls. 👍 That, and wear safety goggles to keep metal debris out of your eyes!

Yes!!! Safety glasses *and* face shield. Those chips fly everywhere. The stronger the motor in your die grinder the more they fly. I had a painful trip to the ER to remove a chip from my cornea. T tried to flush it, brush it, and flick it away by myself, but just made it worse. Even tried a magnet. I had some pretty good wrap around safety glasses, but apparently not good enough in that perfect storm of chips. Next time I'll add goggles or face shield to my list of required PPE.

Tip, if you are grinding aluminum use wax on the burr to keep it from clogging. Old candles work well. Cuts better too. Go for a multi angle valve job, as Smokey Yunick said "the valve is the obstruction in the intake path."

@460efiguys3 Жыл бұрын

Something else to try as Wax just flings... For aluminum what's even better is a mixture of wd-40/ marvel tool oil and a touch of dawn to make it cling. We use that combo no matter the carbide type when working aluminum.

Great video; direct and simple to follow instructions. I used the same Harbor Freight Die grinder and have one suggestion: use a speed control. I bought designed for a router (universal motor) for around $20. This allowed me to slow the die grinder and the difference in controllability and smoothness of cut with the carbide burr was amazing. I made it most of the way through one head before I tried it and as a result the second head went much faster and I had better control. An added bonus was that my hands didn't feel like they were buzzing after doing the second head.

When you're going for economy, it's not about maximum flow, it's more about EVEN flow. The more even the cylinders fire the smoother the engine runs and the more economical it will be. The best way to ensure even firing and even cylinder contribution is exactly what Tony showed here, just form the ports to the shape the casting was intended to be so they are all the same size and shape for smooth, even flow.

Professional engine builders might have fancier tools to do it with, but they're all essentially just a die grinder, and they also do it by hand. Mass manufacturing practices cause the castings to rarely come out anywhere close to the exact measurements, shapes, and designs that the engineers intended when they were drafting the actual blueprints. The only way to make the castings match the original design is to reshape them... with a die grinder... by hand.

awesome video, i always hear people talking about how porting doesn't yield much in the way of results but they are testing modern engines that don't quite benefit as much as these older castings with non canted valves and fairly primitive designs that don't necessarily lend themselves to laminar flow from the factory

@Carstuff111 4 жыл бұрын

See, this right here is what I was trying to explain to a friend!!! That as long as you clean up the ports, remove casting flaws and make sure the area behind the valve has good flow potential, it would open up some extra power. It isn't just about opening the ports as big as they can go, but just cleaning up the path already provided. And I had experience with that with a high compression Honda B18A1 that started out with just a basic clean up of the intake and exhaust ports, what little work was needed. This said, when the head was fully ported to match the new performance intake manifold... there was an even bigger gain. This said, nothing compares to the now VTEC head on the same high compression B18A1, with its port work done and its performance intake manifold.

@Spookydude3 3 жыл бұрын

a good tip especially for people who may not to confident with a die grinder and/or uncomfortable working around the seats, look into getting some guards 3d printed to protect them. the ones I made for my engine were just 1.5mm thick and cover the contact area of the seat and 2mm below it. if the cutting head of the burr hits them it will grind through in about 2 seconds, but that's 2 extra seconds to get the cutter away from the seat when it would have instantly damaged them without the guard.

the basic simple porting job, BRAVO! each flaw can knock a percentage of power away. investment plaster castings (jewelry) are smaller but get flaws just like sand cast will. putting all the lines straight+smoother is going to open it up 4-5% at the least, that nugget in the header side was at least that much all by itself! what you just showed combined with back facing the valves will do a LOT for making torque power out of this DD project... piston flipped 360 stroke with the "doctored" 318 heads, really nice oddball combo to start with. it'll likely out-do bottle rocket (unsprayed) when done.

That was a very helpful video. Takes all the voodoo magic out of porting and polishing and gives you confidence to get after it yourself. Thanks uncle Tony!

Smoothing...is one thing porting is an ability that can be pretty involve takes many yrs to get proficient at Most YT vids are "what not to do" lol

One of the common tems we all know is the "bowl". But I like to think of it as the "bell": done right, that is the basic profile you get on an intake port if you sawed the head in half - rounded on top, a slight taper to the walls, and a roundish flare at the opening where the valve seat is. Thanks for keeping it simple - improvements don't have to be race winning to boost the fun factor of a daily driver.

I hand ported my 225 slant 6 in 1974 using the same methods, I have done my motorcycles and chain saws as well. it works well.

you are very lucky. when i was in your age bracket, i had to have at least 3 - 100 watt light sources (or work in direct sunlight) in order to see well enough to port heads. and yeah, i learned the hard way about brazed carbide cutters. only back then, the solid cutters were in the $10.00 - 25.00 each range. i miss working on engines so much. it was the most satisfying thing (except for the kids) i ever did.

Very helpful for the new engine tuners. Keep it simple is the idea, especially for a road runner. The only things I would add is the use of a strong magnet or vacuum cleaner to pull the ground metal away and wearing a dust mask and goggles.

Following this build closely getting ready to do a build almost identical to this one. Starting with a 360 from a 1974 motor home that I picked up super cheap. Runs great now but needs all new gaskets and freeze plugs from sitting most of it's life. Motor and trannsmission have 74,000 original miles. Want the same type of build you are doing for a fun little daily driver. Drive train will be going into a 1980 D100 short bed 2 wheel drive. Thank you for sharing your knowledge freely so others can learn.

I guarantee the exhaust seat by the heat crossover is sunk so bad it can't be fixed. So, good heads to practice on!
