I don't know what exactly you're working on, but.....if I put scenario #3 in my engine and 58cc heads, I'd have 8.2 static compression. My quench would be .144.
(BTW, I've got a small block Ford stroked to 331. Flat tops (-6cc), zero deck, 58cc chambers and running about 10.3:1 static cr with a .039 head gasket. Quench is .039.)
