Well, I finally had a chance to tear ton a short block that previous owner clamed had no low compression. As seen, the cross hatch is very visible, but there seems to be some cylinder/bore "wiping" as well as heat marks at the very top of the bore.
I know its fairly diffult to judge just based off pics, but if the bores are still uniform top - bottom, can this be bored over 0.5mm/0.020 and be fine, or do you think a bigger overbore would be required??
