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?
