Check Amazon for David Vizard's How to Build and Modify Chevy Cylinder Heads. It's all in there. The guy is a real pro.

Published by HP books. Only problem is it's about 12 years old, but the principles should still apply, and he's very scientific in the way he goes about things--he doesn't subscribe to myths like "gasket matching" to the point of hogging out the intake ports. Rather, he says, (and to paraphrase), it's more important to determine that anything we do has worthwhile results.

You might also email nighttrain66@msn.com--Lloyd Elliot. Very helpful and nice guy. Also ports heads for a reasonable price.

 

yea, im gonna have Lloyd port a set for me later this week,
ive check that book out and im gonna get john lingenfelter's book
on small blocks. he talked about port size vs volecity, thats what i was interested in.

i might still try and port this extra set i have, but im wondering how much it would cost to get them flowed?
