closed chamber BBC heads are the worth messing with
i might be buying a .030 over 454 with closed chambered heads on it not sure of the casting number says there 66-67 396 heads oval ports the engine has flat tops the guy that built it thinks that makes a 10:1 motor i tried to correct him it's not even 9:1. if i stroked it to a 496 later on down the road it would make 10 with flat tops but just out of curiosity are closed chambered heads on a BBC worth messing with can the support 650 hp?
