seriuosly though

you said that .015" variations in chamber depth were matched and made flat by hand grinding and polishing?

being a machinist this impresses me - you did this by die grinder? with carbide burr then polishing stone? then measuring at random locations to ensure flatness? this is cool , not being a mechanic but a marine/aviation machinist we fit and hand scape plenty diesel engine parts - I trying to overcome my novice gas mechanic skill i gotta start applying my machinist trade to autpmotive use

you fellas help - ya learn somepin' everyday

Yes, by hand. With first stones, then sanding rolls. You can only get so good by hand so "flat" is a relative thing, but most if care is taken it can be done pretty well. The depth mic was more of a "go-no-go" gage. When it was flat on the gasket surface and the marking dye was rubbed off evenly it was basically flat. It was years ago when the quench domes first came out and nope, I wouldnt ever do it again. I once heard a rumor that when they were hiring a machinist Ferrarri would give a guy a file, a mic, and a chunk of metal, and some dimensions. He had to get it perfect using the file in every dimension. Those that took the time and got it perfect, got hired. I forget where I heard that...lol.
