Satisfied that it was 1.560" and failing to take notice that the crown was ( -3.5 cc's), I blessed them. I must have been in a senior moment or a semi-coma to put the OK on those pistons. They would work OK on 72 or 76 cc heads, but will not work with 64cc heads on pump gas.
I feel like an idiot for misleading you, but rest assured that it was not intentional.
