That depends on the shop, the tooling they have, and the ID of the bushing. Reaming lifter bushings is really a tough job. Especially if doing it by hand. Honing is super slow, but accurate. When I have BHJ make my bushings, I size them so I don't have to ream them. I go for a .002-.0025" press fit. I try to have the ID about .004-.005" small once installed so I can just hone them. Honing from the OP's .842" nominal size to a .903" would take hours and probably wear out a set of stones. In his case, I would ream or drill them if I wanted to reuse those bushings. He would need to see if his shop has 2-4 incremental reamers to do this. Can't ream .060" in one shot. There is allot of advanced tooling and cnc processes out there. I have no idea what his shop may have available. In my minimal old school shop, we have a vertical mill and a rollover fixture. Plus the BHJ tooling. If I was reusing his bushings, I would have to drill the bushings within a 64th of an inch. Then hone the rest of the way. Or he can just start over. He can save a couple hundred bucks if he reuses them and they can be saved.
