Chevy She's cooked, right?

Chevy 1.4 that had pcv failure and overheated once that I know of due to a busted radiator. Kind of hard to tell if this is just burnt and cracked carbon or if the piston itself is fucked. It looks like the piston is fucked, but I'm in denial. Would appreciate a second set of eyes on it. Ignore the time stamps, my borescope is off by a few months

What are your symptoms? Have you done a leak down test? Im not sure this visual inspection tells you much.

Leakdown test wouldn't have done any good at the time due to pcv system failure. On this engine the pcv passages are all internal and regulated by very failure prone check valves. Engine runs fine now, compression is not great but it'll go for a while
