dtw- your valves look good. However, don't your cylinder walls look a bit scored?
The resolution or focus is not great and I think I can still see some of the cross-hatching, which is good, but there is evidence of vertical striations.
You didn't state total time on cylinders, and this may be normal for an older engine. My guess, so long as no significant compression or oil issues, nothing to worry about.
Any engine expert comments....?
