While rebuilding my L98, right after putting the pistons in, I noticed that I must have gotten something in the wall because there’s a light vertical scratch. It’s deep enough that I can feel it with my fingernail.
Should I re-hone this cylinder? It’s already been honed once and is about .001-002 over (pistons and rings are stock 4.00).
Were the rings deburred before installation? The end of the rings may have a slight edge which then cuts into the wall. I can't see what else you may have gotten in there.
Pull out the piston and see what caused the scratch, you want to eliminate that issue for sure. Once you get the piston out you could try and run a flex hone in the cylinder to knock down any edges on the scratch and then see how it looks.

Yeah, I was thinking that too. Pulled out the pistons, have it another home, checked the ring ends. It’s now at +0.0035 but I think that’s be good enough for normal wear and tear for the next few years or till I do an LS swap.
Re-hone?
