Honestly.... what rocker situation??? I've used them at .650" lift and the swipe pattern is fine on a 15° head... only thing I can see as a upgrade is the Harland Sharp bearing upgrade to the stockers.

The question was posed as to if there is another stock gm rocker besides what I have on my 241 heads that will I could upgrade to ..for example maybe the LS2,6,3,7, etc... stock rockers will work on my car or all the rockers the same from the factory ( I don't think so)

All cathedral port LS rockers are the same. L92s are specific as are LS7s and thay don't interchange with cathedral port heads.

AFAIK and have observed during teardowns of the rockers, the bearings are the same. The only "upgrade" is the $260 Harland Sharp bearing/trunnion upgrade. I'm surprised other companies haven't offered this service. Of course, that sorta admits that the stocker isn't so bad.

FWIW, the "stock rockers suck above .550 lift" info comes from Trick Flow which sells LS heads with 13.5° valve angle vs. the LS 15° valve angle. That 1.5° does have a bearing on valvetrain geometry.
