I bought a set of the stainless ones about 10 years ago that had heat treating issues with the adjusters . When the adjusters go "tink" and fall inside of your new motor, it's a very bad feeling . I had the same problem. Comp adjusters solved that. Roller tips gave up next. If I could get the rollers replaced I'd put them back on. Kevin

What sort of cam are you running? If it’s a solid roller, don’t skimp on any valvetrain gear. If it’s a flat tappet cam with mild spring pressures, most rockers will survive, but I agree with others that in general needle bearings should be avoided. There’s literally no advantage and the potential for disaster can’t be ignored. I’ve been running a set of bronze bushed stainless PRW/ProComp rockers on my solid cam 451 for nearly a decade. I typically do an adjustment and look them over closely each spring; so far so good. I’ve had them off the shafts a couple of times in the last few years for various reasons; shafts look great.

I have the Mancini rockers, they're a pretty nice rocker for the money I guess. The adjusters I have not had a problem with, not sure if they've changed them or I have the china ones, but they don't seem like total junk to me, I bought mine in 2013.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street
