Im building a 346 stocked to a 395. I was wondering if it would be worth the money to port and polish my heads or go to a 205cc or 215cc head.

 

If you have the $$$, a set of AFRs would be my choice...cfm + velocity = power everywhere . Is this a track only car???

 

ok we need more info. I can say some companies can port a set of 241 heads to flow as much as aftermarket heads. do your research and check the post by tony mamo about cylinder heads. what is your cam, intake, exhaust, power goals, requirements of the car?
