I'm sure someone on here has replaced their factory rocker arms with roller tip rockers by now. Ive only been able to find a few manufacturers who seem to have good reliable parts reviews. When I originally rebuilt the top end about 10k miles ago I done the trunion upgrade. Now im just trying to free up a little hp with roller tip rocker arms. Ive found the harland sharps and Scorpion racing rocker arms that seem to have decent reviews. I looked at the summit racing brand ones and they look identical to the harlands that were the same price which seemed odd but whatever. has anyone tried the proform brand thats sold by summit racing ?

I bought Proforms back in the early 2000's and ran on a set of GMPP Vortec heads on a 350. They worked great and I still have them as I upgraded to 1.6's on the engine. Personally I would save your money. I assume you are running a 4.8/5.3 since you mentioned trunion upgrade.
