Ok guys, here is the deal, i have a 1977 pontiac grand prix with a 77 olds 350 rocket that came in the car originally. I have little car knowledge but im trying to learn and i need some help. Someone on here said it would be smart for me to get some new heads in my search for power. He suggested #5 or #7 heads, is that right? and who has some for me?

 

You have a PM.
