I've seen some of the same on one 254 I bought, was carbon scored, guess the csrbon cake went loose when they changed fuel from pump gas over to Aspen fuel. The only diff was that the most of the damage was on exhaust side, just a bit on intake side.
Not like this though.

No marks at all on top of the piston? Someone else put fuel in it for you when you cut up that oak? More pictures please!!

multi point piston seizure can be indicative of a piston that's too tight for the bore.
