I currently have the Comp LS trunion kit for my 228r cam(haven't finished install yet) but after reading into other peoples experiences a little more I'm thinking about going back to stock, or the EPPS LS Rocker Arm P/N: RA-6642. Anyone running these? Thanks.

 

I assume you mean EPP? I am not sure exactly what the animal is. If I had to guess, it is from the OEM mfg of the GM rocker arms or even a rocker that normally is on some of the non-LS GM stuff that uses the same/similar design. Might even be the doing of Jegs or Summit? IDK. They also offer an "upgraded trunnion" model.

Anyone else familiar with these?

Yep I meant EPP heh, reading about EPPS cams caused that slip. I was looking into it while following the Straub Bushing kits. Went ahead and bought a Straub kit since I'll be putting more than stock strain on the valvetrain
