I pulled out my exhaust valves and the one on the flywheel side is scratched. I replaced one a couple of seasons ago when I rebuilt the engine with RK Tek head and drop-in kit because it was also scratched. The cylinders are not the originals. The pistons look good. Is this anything I should worry about or even replace?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
