    looks like something was in the cylinder and the piston and head took a little beating from it.

    Looks like something got in there and banged around.

    That is detonation. There is a chance that it continued down the side of the piston (on the side that looks "cleaner").

    On a stocker, I would pull the pistons and look for any wear on the sides. if there wasn't any, then I would clean them up and reuse them.

    BUT on a stocker that probably wouldn't happen. On your set-up I would replace (obviously, forged is a lot less likely to do that).

    Not saying you HAVE to do it. Just what I would do. I don't like hot spots and changing weights on pistons (if you clean it up, you will lose some weight) when you are running more than stock.
