So if this is right then this piston will be - .072 in the hole before decking the block right?

Bore Blck Comp height 73cc
232453 4.375 10.699 1.858 10.1


Dome Vol Gram weight
-28.9 710 grams

What would compression ratio on this be with a 75cc head and a .20 head gasket with surfacing .010 off the block????
