compression ratio is the volume above piston at tdc added to the value bellow or bdc or bottom dead center. then deviding the volume above to give you your compression ratio

So .039 and .038" is the same volume above the piston so compression will be the exact same thing.

I will explain better later

I get what ur saying about the quench being the same. I was just thinking about the .014 thicker gasket being more susceptible to failing. I am perfectly happy to use the thicker gasket with the piston above deck .015. So is there any theory that a thicker gasket will fail b4 a thinner 1? Or with a thinner gasket does the head get clamped to the block better cause of less gap. It would that even be a concern. I’m trying to learn. Kim
