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...
