Combustion chamber size What are the advantages of different chamber size on 243 heads. I know it affects compression but how does it affect flow and HP? What would be a good chamber size for 243s on a LQ4?

What are your goals? Depends a lot on piston relief and cam. We also need to know how far out of the hole the piston goes and what head gasket you plan to run. Then finally, what octane gas do you plan to run?
