New Heads?
 

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?

Specifications:
* Advertised duration: 270 intake/270 exhaust
* Duration at .050 in. cam lift: 224 intake/224 exhaust
* Gross valve lift: .501 in. intake/.501 in. exhaust
* Lobe separation: 110 degrees
* RPM range: 1,800 to 5,800
* Rough idle

this is the cam i have it is the comp. cams mag. and what type of heads should i get to match this?
