Need advice cylinder scratches

They did a crap job of cleaning the bores, or some debris found it's way between the piston/ring/bore surface. It would bother me, but I wouldn't take it apart for that. I've found worse in engines with a lot more miles... One 360 I took apart had been rebuilt but never run. Good thing too - 3 of 5 main bearing "bottom" shells were install in the "top" saddles in their respective bores...
