I was asking because to my knowledge, with a 2.500 cam tunnel bore - you can run either 55MM roller bearings or 60MM babbit bearings. At one time I thought I was told that 60MM camshafts were all made out of billet cores which still requires roller lifters (no flat tappet stuff). I am running a non-boosted cam with a net lift of .706 which seems to require lifter changes/rebuilds at 8K - 10K intervals. I would really like to find a source for cam bearing spacers so I could run a 55MM flat tappet - I would gladly sacrifice some power for longevity.
