porting your own heads
porting your own heads
Has anyone done it? What's involved in doing it?
I'm thinking about doing my own set of heads, cams, and primary gears for the winter but the only question I have is reworking my own heads. Looking for a little guidence here.

Most of the shops that do head porting have invested many hours on a flow bench and probably many thousands of dollars in learning just what port shaping and re-contouring is required to make the most of a particular engine build. Some will require having the ports partially wended and reshaped. Unless you have the equipment and the know-how the chances of your seeing any measurable gain after attempting the job your self would be slim. Going fast or producing big torque is costly and going fast or producing big torque reliably is even more costly. I have to agree with Donny I, It is a job for the Pros.

I could probably sew up a gash in my arm, but think I'd prefer a Dr do it.

I agree unless you know where and how much material to remove and reshape, your just guessing as to what is gonna work or you might ruin a good set of heads. plus you have no way to test what you have done.the pros make it look easy, but there is a method to they're maddness,,,,,

RE: porting your own heads
Personally, I applaud your enthusiam. Obviously it's a job for the pro's, but I think you could make a minor improvement in performance by just knocking down the rough spots in the ports. I wouldn't get anywhere near the valves or the overall combustion chamber. The stock heads I've seen had some pretty nasty casting marks in the ports. Not sure you would notice any improvement (maybe not even on a dyno) but the satisfaction of doing it would be pretty cool.
Go for it.
