I guess Comp Cams doesn't make the Magnum Self-Aligning Roller-Tip Rocker Arms anymore, but I did find these Scorpion Roller Rockers on summit.

Are they good, and reliable?

I am running them on my motor, no issues, you can definitely hear them, but I installed as part of a cam swap, so tuner knew to do something with knock sensor readings ( that’s all above my pay grade) lol

IMHO I would spend the extra $ and get the Crane Gold narrow body, made in USA

Good article on Rocker arms for us: Rocker Arms 101 - Everything You Need To Know - Vette Magazine

I had a couple of Crane Gold failures, and I switched to the Comp Pro Magnums (not self aligned). Those served me well for years, although I understand you are saying they might not be made anymore.

I run the old GM Performance SA 1.6 full rollers. Not sure if they're narrow or not, but the fit under stock covers. Believe they were made by Crane.

I'm running the GMPP's as well but would really like to add guides and switch to Comp Pro Mags one of these days.

There is still Crower 73603-16 and 73603-16 but, yes , you pay for them.
To me, kind of the gold standard for this type of rocker.

The Scorpions, I have no experience with them.
Try Googling
"scorpion rocker failure"

Edit , I am not recommending self align rockers as I am not a big fan.
I think the valve and guide have enough work to do already

I am using the Crowers with my current build. Not cheap but I plan to work this engine and I sprung for quality parts in the hopes it would offer some reliability.

The Crane, or GMPP, aluminum "narrow body" RR fit under the stock VC fine but Comp "Pro Mags" and others require minimal trimming of the baffles in VC. No big deal

IMHO I would, and do, run NSA RR and guide plates. ISKY adjustable ones

I ran their SA rockers in the past without issue. Clear valve covers fine and were made in USA, I believe they are in Florida. I would not hesitate at all to run them.
