Sorry guys, I disagree.
At the very least I would pull the pistons and inspect the rings and piston lands for damage before I'd even think about putting it together.
Bottom line, something caused this, putting it together without knowing what could be very costly. If you pull it apart and find a bad ring or two, you're only out a few bucks and a little time. On the other hand, you run it with a broken ring and you could be into new pistons and boring it again. If you decided to take the risk knowing the consequences, great that's your choice. However, by what I see in the picture, I wouldn't advise someone to gamble site unseen.
