'True' Factory Compression Ratio's

I've only owned one 383 commando in a '68 Fury. I took off the 906 heads to have hardened seats/new valves installed, and my pistons stuck out of the block at TDC at least .010, maybe more. I did not measure them, but it was visible by eye.

we found the same with a 68 Fury Vip, maybe not .010 , but above deck.
