If the reground cams are not hardened you're not going to have lumps on
them for long.

Subject: Lifter Hardness
After destroying one valve train, I'm trying to do things right this time.
I took two sets of new lifters (one from TRF and the light ones from Moss)
to be hardness tested. All of them tested less than 30 Rc, i.e. no
hardness. From what I've read in the archives, I should have at least 56
Rc for a racing application. Does anyone make decent lifters, without
going to the smaller GT40 lifters? I'd like to stay with full sized
lifters. Has anyone considered having lifters made or having the soft
lifters hardened? Do we know the type of metal they are made from? Ok,
and now for the stupid question. If the reground cams are not hardened,
why do you need 56 Rc lifters? Larry Young Forever Young Racing
