Are they flat on top, slightly dome, or slightly dish? Mine are 9.5:1 and they are slightly dish. We measured the compression height, and even cc'd the combustion chamber, so it was accurate.

flat top with valve reliefs slightly dished. i checked diamonds specs to see what they show, and they say stock comp height is: 1.257 does that sound correct? if so then i'm good. if not i'm screwed
