Thanks all for the replies, some good food for thought. I've attached a drawing to help clarify. Apologies for my drawing to the artists and engineers out there. The Park bushings rest on the inner shoulder of the cups, not on the race. This was second time I've used them, first time was for a modern new 1" Record headset. This Athena headset is from a 1989 bike. I can't appreciate any type of residue that looks like glue. I got the bushings to help keep the cups straight while pressing in, and they do a nice job of that. I'm going to mull over options. I'm hesitant to use the actual bearings because I think the pressure might deform the cage.
