Our shop used Crane in mid/late 90s early 2k, then Crower, for the Busch and Hooters Pro Cup, ARCA, Craftsman.etc Roller stuff.
late Sb2 and early R07 was Jesel keyways.. All of the rollers we used had needle bearings, rocker arms too.
The shop my buddy worked for Used morel and only morel. they were needle bearing as well.
I think brand may mostly be team or builder preference.
Rocker arms were the only things that would go on our stuff, mainly from spring pressure being lost. but that was yeeeears ago. Not because a needle bearing.
Needle bearings were used as am bearings.. no harm there either.
I think proper spring rate and lashing along with bore clearance makes a lifter last. Sure oiling does, but less than you would think. Saying you need to go bushing because everyone else does is bandwagon.. and like I had mentioned earlier, I have customers with thousands of miles per year on .8xx and higher lift cams, and 800-1100lbs open pressures on needle bearings. most use Crower. some have Herberts or Howards which are morel. but I never use Comp, its a personal preference not to.
If you plan on letting your lash get way out of whack go for the bushings, and keep an extra set of pushrods and rocker cups too.
