Alright, got some measurements to share after pulling the block and getting it on the stand.
Deck Height = 0.048"
Piston dish depth = 0.030"
Approx dish diameter = 3.150"

I'm going to pop these # in a CR calculator later and see what my approximate CR is with 64cc heads. Only thing I dont know is how thick the head gasket typically is... Is 0.020" a good number to use?
I'm strongly considering sending the block to my machinist to have him disassemble and hot tank. The damn thing is a dirty mess and the cylinder bores have some slight surface corrosion from the coolant getting in them (I have pics). I've also been tossing around the idea of installing some flat top pistons. I will run the CR calculator with a flat top installed and see what I get. Hope everyone had a happy Independence Day.
