Head flow

Heck, he might even tell you what they flow. STeve His Spirit runs real well and it has iron heads on it. Either he has some of the absolute best flowing AMC iron heads or his engine builder Barry Allen has some AMC efficiency tricks up his sleeve we don't know about   I bet Jim would claim that it is his tune that makes the difference !   His Spirit and mine ran real close to the same ET when I last had my car running.....and last time I had my race car running my Indy SR heads were flowing in the 315 range on the intake side.

310@600

Is that the fastest factory head car without epoxy?

Anyone have heads with epoxy? What are the problems that you have to watch for and how hard are they to work with?

You don't have that much flow because Dean Turk didn't do your port work. When Don Garlits came out of retirement to attempt to break the 300 mph barrier he chose Dean Turk to do all the port work on his cylinder heads and manifolds. Thats how good he is. He has turned away work for years because he's always swamped with work. He will only do port work for true enthusiasts and always achieves the best flow numbers. Dean has been retired for many years, but still does the best port work in the country for a select few. He was a pioneer and early dominating force in the early 60's, First in a Pontiac powered Fuel dragster and later with a Crysler Hemi Fuel dragster.If you don't know of Dean, then you missed out on a truly fine human being that would be just as excited as you are to see you (and help with the best possible porting) tweak as much performance as possible out of your AMC.
