IMO the best rockers for a H/C/I LS car is the stock stamped rocker with a trunion upgrade. Even the LS engines in development for NASCAR are keeping the stock rockers.

For a mere $135 you can have upgraded rockers.

I thought aftermarket heads had bronze valve guides, thus the need for example, Yellaterra rockers to allow for adjustment of the wipe pattern, to stop the scrub motion from wearing out the valve guides.
The trunnion upgrade on the stock rockers is to stop the needle bearings from falling out, correct?
