Re: chamber volume

It'll vary. Especially if the heads have been milled. The valves maybe flat or concaved.

If untouched? 72.2-75.2 for an OC head. It can go anywhere from there.

Re: chamber volume

US opens run 74~80. Mine are 74 and have been cut .020. They were in the 76~78 range before trimming. I have measured some 4V opens as small as 69 - not sure how that happened.
