Its good to see the younger generation putting down the social media and getting there hands durty you truly cant learn how to run a die grinder in a port tjrew a book or class unless its hands on keep on porting dont let a set of heads performance determine whether you keep trying

Killer video bro,,,tip 1 always get the heads looked at first to make sure there good to Go,,before doing all that work,,2. Can’t wait to hear how they are working,,good Job

Ports look good! Try setting the throat diameters at 89% intake valve and 87% exhaust valve fully blended to the bowl. JD

I got a set rn I had for 3 years well time to get at em thanks for the inspiration keep it up bro 50 gang!!!!

Your ports are going to favor the radius on the roof when the radius is trenched out causing paddling you cant make air go where you want let it flow where it wants it does not matter what they loook like its the port taper and bias that really helps most important is the valve job + 1inch in and OUT the valve what you havr done wont kill the power but there is alot on the table gt40 ports are very unforgiving e7s are much easier to get power and flow out of sont get stuck on flow numbers

Looks good.

I cut threw in places especially the push rod tube and brazed them.up you can weld cast iron its not as difficult as everyone makes it out to be most head porters have become complacent as the industry went full on aluminum which cut porting time down significantly installing complacency in most of us i didnt rouch a set of aluminum heads to fully port untill around my 15th set of heads for verious customers .what was wild was working at a uncles machine shop building engines learning the machining process these customers would drop off a set of heads or engine from there altered, dragster ,pro street,sportsman classes of cars you should have seen there faces when they learned all that power was done buy a 13,14,15 yr old teen .. you dont race flow benches so flow numbers are nothing but a tool he taight me how he used a flow bench many sets of heads later his way of teaching was down right spot on.. all you are doing is constantly fixing another problem or situation inside the port whether it bee air speed or shape/SIZE WHICH IS THE PRIMARY AFTER YOU GET THE PRIMARY RESTRICTION FIXED FIRST AND THENNIT SHOULD STILL BE THE NUMBER ONE RESTRICTION WHEN DONE ASK YOUSELF WHAT IS MOST RESTRICTED PART OF THE PORT ?????? ALSO AIR HAS MASS IT HAS WEIGHT . HOW DO YOU MOVE AIR ALSO YOU CAN NOT BEND AIR IT WILL FLOW IN A STRAIGHT LINE SO HOWM DOES IT GET INTO THE PORT IT HAS TO DO SOMERHING TO MAKE IT FILL THE CYLINDER.

Puliste demasiado la admisión carnal.. de ahi en fuera todo bién..👍

Good video do yourself a major favor get a safty shield especially when porting cast heads dont ask why trust me its not fun spending hrs at er getting a cast sliver pulled out your eye

Those intakes will puddle bad you want a very rough finish like 36 grit use your flashlight look for shadows low and high spots make them all even . Tbt that isthe only visual part of porting which after about your 5th set of heads you should know how to cross cut a prt with burr to make even flat port walls the worst is always the roof or floor being so narrow you want to just side to side the burr its natural you have to angle it then angle. Across last cut making as close to an X patern as possible or do the lift technique only cut in one direction when u lift move forward or back very little at a time keep practicing stop wasting time polishing the ports you would be better off leavingbthe burr ruff finishb then polishing i guarentee those heads with just a burr finish will do alot mre in terms of power then shiny ports we are men we love shiny things look up fuel puddling and what pop and bang means when fuel puddles i promise you i was porting gt40 and e7 heads in 1992 was my first set of heads i ever ported they were mopar heads for my first car

Thanks for taking the time to do this, I'm currently porting my 3bar heads for my 351! Did you match up the ports with the intake you are using?

Coming up nice, pitty we cant take much of the windsor heads. How much horsepower gains would you estermate

What are the flow numbers

Found yr YT on yr Chevy trail blazer

Why didnt you weld the thermal holes first. You will not only loose flow but your vacume during overlap will drop.
