achieving .035-.040 quench is critical



This has me curious. Given a .040 head gasket thickness this means there has to be zero deck height. Correct ??



yes . with a closed chamber head , with an open chamber you need a D shaped stepped dome and in the case of cast iron heads you need to equalize the depths of the open chamber across the head , they are anything but flat and equal .
