I'm Awesome
I'm favorably impressed by much of what you've accomplished and appreciate much of the knowledge you've shared; but here, I Disagree in both application and principle. Again, and like a dyno, Spintron don't lie. Also, (understatement) I have more respect for GM Vortec heads than you seem to. Opinions.
I'm selective; not one size fits all. Overall, stamped RAs (including OE) work rather well and live long, even in extraordinarily harsh conditions; reference GM's L31-based "602" CT350 campaign.
FWIW, stamped RAs are good candidates for cryo as well as for lapping-in their pivot-balls.
Cheap "roller tip" RAs are known to fail at tip with short MTBF; when that roller tip affects friction reduction little-to-none. Accident looking for a home; Not always so durable. Every motor/build don't rate top-quality full-roller RAs; and cheap full-roller RAs carry too great a risk for failure. Your $ your motor.
Notwithstanding my above positions, I do also run quality full-rollers; when and where they're practical.
I wish crane RAs were still available new; I still have sets of gold race. I wish they'd continued to develop their hybrid which was essentially a gold race But, instead of a roller-tip, was shod with a precision tool steel slider "shoe."
I have found stock ones wear very quickly, using oils today. My L31R was eating on them heavily with under 30K miles on it. Also work on a 2019 L31 powered generator that was eating on them noticeably. I miss the factory GM LT4 rockers myself. Was easy to pickup a set of them on a car someone was building for a truck engine. The LT4s had a nice net lash system as well when using the OE rocker studs for them. I actually prefer the net lash when using a stock base circle cam.
