Does anyone know the combustion chamber size for the L98? I seem to have a brain fart. I remember hearing 58cc, as well as 60cc, but I'm not sure. I'm finally replacing my heads, but I don't want to take a hit on compression ratio. Thanx.

 

Yeah, it's 64cc for the iron head (camaro&firebird 350's) and 58cc for the al. L98 (vette) head.
