Default combustion chamber sizes
Can someone give me a list of the different combustion chamber cc's for the various LS heads? I am particularly interested in the difference between an LS6 "243" and the LS2 "243" are they the same or will an LS2 head lower the compression ratio on an LS1 engine?
Thanks!

Default Ls2 = Ls6
The LS2 heads use the same casting (243) as the LS6.
