Pieces of steel in cylinder??

Would the pieces end up in all cylinders?

I failed to mention I did find a bent push rod on #7 exhaust valve. All other push rods seem straight.

Is number 7 bent push rod from same cylinder with the exhaust valve sunk low ?

That would make sense bending the push rod as the seat was coming out of it's hole. May have bent that valve stem there too.
