I glued it overhanging by 1 /16" so a knife edge against the head. Dang, head was straight as a string in all directions, diagonally etc. Could not get an .001 feeler under anywhere. I could not figure it out but then,,,, I saw the little freeze plug I was gonna ask you all about but keep forgetting to. 30 seconds with a flat file and case closed. No rocky head. The freeze plug was .008 proud of the surface. Both heads have one. Why was this done?
