220 will be smooth enough, just want to knock off any tiny chunks that might come loose. Damage appears to be from either the crank spreading or piston/thrust washer/bearing fragments. Bearing bores are fine !!
Alright sweet thank you! I think it was from the crank speading bc all the bearings and piston were fully intact on that motor when i got it,just the crank bearings on one side seized up nd toastes the crank,piston cracked in a few spots but stayed intact luckily
