Porting stock heads

[Vip18971]

I'll probably slap a Performer RPM or a Victor Junior intake on it, but it seems as if the flowbench which I do not own is pretty important, so I might just send them off if nothing else. I was just trying to save a few bucks by doing it homestyle, although I'm sure flow benches would cost more than sending the heads off to have them ported/milled/whatever else needs to be done to them? How exact is exact for the car to run right, anyways? And I'll look into the carbide burrs and sanding rolls, thanks for the info, jrgoffin.

83Mustang, they don't look bad, just messier than stock Although, mine will probably look worse, was just asking about porting those cheap stock iron heads - I'd never home port a set of Vic Jrs. I wouldn't mind having homedone heads that flowed better than GT40s...

Remember flow isn't everything. Lots of things work together to make a good set of heads. Port velocity, turbulence, flow etc. etc. You aren't going to sit down the first time and get a set of D7e's to perform like a set of AFR 210's ... but it's pretty easy to improve the performance of stock heads ... Just a little short side radius work, some simple bowl and valve guide cleanup, some port matching and you'll usually have a much better performing head.

Lots of info floatin around out there in cyber space, get an old set of heads and try it, you might be the next Joe Mondello ?

PS: someone posted (on this board i think) quite awhile back a link to some info on porting heads using a thread wand ... i've lost that link and i'd sure like to have it back, anyone remember that ?
