Sorry but i'm not trying to argue with you at all but just because you are running them because Tony recommended them it doesn't make them the best. There is a HUGE amount of data out there to discredit this which i really think you know. I just don't understand why this argument keeps coming up tbh. To each his own i guess but this here is how i feel

You are entitled to your opinion just like I am.
I never said they were the best you can buy.
My experience with Yella Terra has been quite positive.
I had a set of of the gen 2 rockers for nearly 10 years without an issue.
The data out there has been mostly from the gen 1 days 15 years ago but it just seems to keep popping up every now and then.
Personally I would never use any stock rocker above .600 lift for various reasons discussed previously but each to their own.

Spending money on a high dollar rocker for a hydraulic roller setup seems silly to me. If I was to buy a good set of rockers, it would be an adjustable set for a solid roller cam, since the cam and entire engine combo would be more serious anyways. For a street hydraulic setup, stock rockers in the vast majority of cases would be better. Nothing wrong with needle bearings either. Less friction means less heat. A quality trunnion like from ws6store is an excellent option.

Ive ran a few sets of rockers. Harland Sharp.... Broke a c clip. Crower shaft mount adjustable...... F n awesome and never an issue. YellaTerra Ultra lites 50k miles...... never an issue and now I have stock rockers with CHE bushings........ so far so good. I did a back to back dyno on my LS3 with stock rockers vrs the YellaTerra 1.85 with GrannyShifting at the helm. This was in my LS3 stock heads and cam 1.85 made 440/397 and stock rockers made 432/403

Once again, Texas Speed roller tip rockers, minimal added weight, benefits of roller, cost is about the same as Yella Terra and half of the upper end shaft rocker set ups, all steel construction, making them less prone to breakage about .( 200” shorter pushrods used). I think that covers all the bases but I’m sure there will be detractors....

This has also been beaten to death.
If you don't exceed the maximum open pressure the rocker is rated too, then the likelihood of issues is minimised.
Stock rockers with trunnion upgrades only address half the shortcomings of OEM rockers.

It's not just about broken rockers. The over the nose weight has been proven to just kill power and valve train. Plus if springs/valves/weights are not setup just right you have nothing but issues. THIS has been proven time and again! Let me ask this then. How come most of the biggest names in building these bad *** LS motors and heads shake their head when you bring these rockers up!? Most of us here are just trying to help people out. To each his own i guess but i wouldn't touch them with a 10 foot pole.

If everything is set it up right with any rocker you will have good results.
I wonder with Mamo's combinations,If the yella terras are such power robbers why do they work so well?
Darth nearly made 700rwhp with still more left in the combination.
Answer:
Because everything else is matched.
Hate them all you like but they work well when set up right.

Interesting thread however we need to wait for the final results.
Josh B was also blaming Tony's rockers for valve float but the issue was all along a spun bearing causing the power loss and wavy power curve.
He went for mod after mod and lost power too which was unfortunate.
I'm also waiting for his new setup to see how it will do.
I still don't understand how a solid roller would only rev that low before falling off.
Sounds to me like improper install or not enough spring pressure.
