I have a 350 chevy engine. block number is 3970014, engine number is CMJ, head casting number is 333882 76cc.
Im wanting to rebuild to get a bit more BHP. I have a pair 64cc camel hump heads will these work on this with plus 30 pistons?

I'm running a tunnel ram with 2 edlerbrock 500cfm, edlerbrock performer plus cam kit and a electronic mallory dizzy.

Any advice would be very greatfull.

The engine number suggests that it only 145bhp.
Thanks Darren
