one more for yall. i may be a little paranoid but i just put all new rings on my pistons and installed them. i checked my gap on every one of them and all were within acceptable range. i rotated the crank by hand a few times and already noticed some marks on my cylinder walls. i had the block bored of course. is this normal? is it the pistons just seating?
