Yes that is debris scuffing.
Actually after a gas bath, I hit them with the garden hose, then the air hose, then visually see if I missed something then the hot soapy water bath.
and the air hose again.
Check the crankcase breather as well as the valve spring area.
Every crack and cranny has to he clean.
Good news is, I don't see and real damage to be of concern.
