I know the comparable sets (shaft, not drop-in) from them for other engines can get over $2000 per set, but they have a few different products. That is crazy expensive, but we all know the saying.

I went through countless numbers of aluminum rockers and finally went with Crower stainless steel rockers and haven't had a problem since. My advice as well as the advice of T&D, Crower and other manufacturers is to use steel rockers not aluminum for street use.

No. I had been using T&D . I now have a large solid roller and run real stiff springs and have had zero issues. Adjustments are much less frequent. The problem with aluminum rockers is they fatigue quickly especially with stiff springs.

I have had zero issues with Jesel Aluminum rockers on street cars that rev to 8k rpms boosted and NA. Even Nitrous cars but at big power levels I do recommend Tool Steel Rockers. I mean I have a hand full of 8500-10k RPM revving customers out there.

Has anyone tried these from TSP? Not for all out race, but just the typical Head/Cam strong street performer, 7K ish rev limit or a hair less. .620ish lift stage 1/2 type hyd cam.

Seems an affordable roller set up. Not sure who the actual supplier or country of origin are.

There's a big difference between Jessels and T&D. I spoke with T&D about the failures that were occurring and after seeing where they were breaking they told me it was from fatigue and they were not a good choice for my application, the other thing I've noticed is that lash adjustments are much less frequent with steel rockers.

$1689 for these little jewels. That's a little too spicy for my tastes.

How’s the rocker arm clearance from the valve cover? Did you run thicker valve cover gaskets?

They came with 10mm spacers but I already have taller valve covers so I won't need them
