What does the head look like ? If the little "centre punch" marks are on the piston and it's supposed to be a loose object there must be some marks on the head. The marks are on the top and bottom of the piston only ! Nothing around the valves ? I first thought detonation but everything is too clean and the bottom of the piston wouldn't have those marks either. Strange...they're very consistent ...same size and shape.
