Has anyone done actual C.R. measuring with the Motoren Israel (Wossner) forged pistons?

The stock C.R. for a R90s is 9.5:1, so I'd like to be sure I have that before re-assembling.
I can do the measuring, calculations but wanted to check here first.
btw, is there a known thickness for the compressed, stock BMW head gasket?
thanks much,
