New Heads?

SmokinStangGT · 04-22-2003, 09:19 AM

I have been having some trouble with my new setup. I put in keith black pistons with 12:1 compression, a nice big comp. cam.,all new bearings and rings, and the motor has been gone through and cleaned. But i am having a little trouble with the lower rpm range, it sems like the car wants to stall out then when it hits upper rpms the car sounds good. The heads are stock and lighty ported, so i was wondering if i slap on a new set of high flowing heads would this help me? The cam is pretty big and people have been telling me i sould get bigger and better heads. And if so what heads would work the best? Thanks.

If your heads are stock, that cam is killing your low end. How big is the cam anyway?
