They can, but it isn't necessary, or recommended. Our rings profiles are cut all at once in pairs on a Wire EDM machine, so the mounting surfaces are almost perfectly parallel. If you are getting uneven contact, odds are your base isn't quite straight, and lapping will only ruin the rings to make them match that warped base. Much better to take the time to bed or shim the base to get it perfectly straight. Then any quality ring will work great without lapping.
