Small block heads with no casting numbers

Number one is close. Those pistons are .05 under without any machine work. Idk if the block has been decked yet or not tho.

The piston head is not where clearance is measured. Don't sweat seeing the top rings. The piston SKIRT is where clearance is measured. Those also appear to be either heavy duty hydraulic, anti pump hydraulic, or solid lifters. I think you did real good! @MOPAROFFICIAL do those look like 2.02s to you or is it playin tricks on me?
