Ive got a chevy 350 bored .30 over and im changing a blown head gasket. I got the head off and noticed one of my cylinders has a decent sized scratch going parallel with the piston stroke. My nail catches it a little bit but not real bad, i was wondering if I could fix this without pulling the piston entirely. Maybe I could hone it out but ive never dealt with a scratched cylinder wall and i dont really want to tear the motor apart to fix it, are there any ways to hone out a scratch without pulling the piston?
