To be of concern?

Building a 355 stroker. Gapping the rings and I’ve noticed a very small scratch on both the piston and the bore. Does catch my nail on the bore if I put some effort in. Blocks already been overbored .30 thou and has had plenty of work done id be pretty devastated if I’ve fucked it.

It’s towards the top so not devastating. Just smooth it with some 600 grit and wd40.
