Default BBC roller rockers?

Hi, had a nice set of crane gold rockers, but during the winter 5 of them has pitting in the tip roller i can feel i with my nail. What is the go to rocker nowdays? I know the t&d and jesel shafts seems to be the best but those do not fit to my budget. Dont know the peak hp rpm but should be in +-6000rpm.

Engine specs
-509cid gen6
-flotek 290cc heads 2.3"/1.88" ,11/32" stem valves.
-johnsson 2126bbr hyd lifters.
-isky 9005 valve springs, 185/470lbs
-comp custom roller 240/245 @050, 0.647/0.647" lift.

I like the stainless steel Crowers, but I have good luck with Scorpions as well.

Few guys has also recomended the scorpions and crowers, but i could get the yella terra platinum pedestals or jesel sportsman shafts for the same money. Some even suggest the comp 1620-16 ultra pro magnum steel rockers, but somehow i dont thrust the comp stuff.

Comp 1820-16 XD rockers for the win. Used them on my last 8 builds and half being blower builds with no issues. Scorpion has had snap ring issues. If you wanna stay stud mount you cant go wrong with the Comp XD's

If the trunnions are good, why not polish the roller tip instead? The tip really doesn’t “roll” anyway - it slides across the valve tip.
