The last photo was with head just pulled. It cleaned up very well with steel wool. No scoring, cross hatches still noticeable.
Should have taken one last after photo.

I am going .030 on the one cylinder, and install new std to .010 rings on the rest.Stuka wrote:Looks like 10 over and you would be fine. I don't know much about those engines or how much over bore is too much. But I would personally go the minimum needed.
