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 ?
