I think I came up with the head clearance with hard measurements, brought #1 cylinder turning crank to the mark on pulley verified TDC, put a magnetic indicator base with indicator on the head deck of block. I checked the top of piston to block deck=.170 did same on head to get depth @ center of where piston dome will enter=.255, I measured a used head gasket as compressed dimension @ .055-.065 used .060. I’m not concerned with interference clearance issue, actually the opposite. I came up with .145 as piston to head clearance which seems to much to me. As Phil Gillespie said he recently did same w domed Pistons & ended up about .060 which is what I was expecting? Thinking compression will be pretty weak @ .145?
