1) None of the vertical marks grabbed a finger nail, but I will check to confirm again
2) Nope, have not checked for out of round (but that is definitely on the to do list once it is fully torn down. This is just a preliminary check)
3) No pitting and just "crud". It actually flakes right off and the pistons clean up with ease
Thanks for the response. It seems a few other people share your same view: This should clean up with a .020 overbore
