I would'nt use them, That's looking for a disaster to happen. Even when resurfacing you're cutting down the hardened shell to where it's just too thin to last. When using a new camshaft always use new USA lifters. Once the foot pattern is established from a new set of lifters and new cam they are not transferable to another cam or lifters. I've heard fo others using used ones but that's High stakes gambling in my opinion.

sure sometime in the past this has been answered,but in tearing down old engines, ending up with alot of lifters. anyone doing anything with them other than tossing or adding them to a bucket of scrap metal ?
