Regarding "fitting to the cam," well that's another issue nowadays since
modern motor oils tend not to support good lubrication of direct

rated lubricants still have the additives to prevent wear on direct
contact engine components.
Roller lifters available for vintage cars including Honda anyone?

You can replace them without removing the rocker shafts, but I have seen a
couple write ups that say they don't go bad for no reason, and the reason
is usually that the holes that feed the oil to the HLAs are plugged. So,
it is possible to clean the HLAs and the holes feeding them oil.
I guess I'll investigate when I park the Mazda and put the Supra on the
