Headgasket looks burned in a few areas mostly in cyls 3 and 4, I’d check the head AND deck surface for flatness, plus clean around that block guard and make sure there isn’t a problem with the block guard or the sleeve itself being cracked right there… Plus look for damage and cracks on the inside of that cylinder to make sure the sleeve is still good and the ring lands aren’t actually broken up too.
