I don't have many miles on mine (LSL lobes, 6600 redline, LS6 valves, PAC beehives) but they seem to be holding up fine. I don't race, but have logged quite a few spirited runs.

The new design has roller bearings also,but much larger in diameter. Big difference is in the bearing carrier. It presses on to the trunnion and the rocker, so it is all one piece,
and can not pop off like the old ones..
I have pressed one apart to get better photos, as they say,
"A picture is worth a 1000 words"

They are "heavy" duty OEM rockers (the needles/rollers are larger) that for some reason were never offered for sale by GM.
Look at the trunion, it is way different.

More info see this thread:

I know of several sets in use for some years now (my friends, my tuning customers), and there are no problems reported.

Our rockers are doing well so far.
No option for different ratios though.

Thats prob a layer of dow molycoat.
How are yours holding up Joecar?
We may have access to a few sets of these so wanting real feedback before we buy some McRibb rocker arms that turn out to be Britney Spears instead.
Ps those references would would mean "back again for a limited time" and "hit me baby one more time" for those that dont know.

My friend (who needed them in an emergency) is still running on them, valvetrain is quiet, oil is clean, car now has 165K miles (I don't remember how many miles ago they were put on, was below at 100K miles).

The sad part is the price did go up (and would go up a little more if molykote option used) but they would still come with our packs of zddp moly lube and may even come with the trunions prelubed with moly grease.
Still well under a normal set of "upgraded trunion" rockers out there (save for ours cuz they are crazy cheap) so maybe not too bad.
Only issue is no offset rocker design so no rect port option.
