I was just wondering if anyone had any thoughts on this. We have a late 69 truck 402
big block chevy that was a crate motor from 69. It has 9.1 to 1 compression with open chamber heads, with the regular 10.25 closed chamber piston. Would the engine make more power if we put the closed chambered heads on
the engine. I know the compression will come
up to 10.25 to 1 but will the heads flow less
because of the closed chamber design.
