Who is running comp r lifters, and likes them? I put a set of comp r lifters in my car. Im having a hell of a time find rockers that will work. Are these lifters work the headache and extra money for lifters? Do i really need fully adjustable rockers?

I run them. Them, along with the new Yella Terra Ultralite rockers helped quiet down my valvetrain a great deal. I have them set between .035-.050" plunger depth which is 3/8-1/2 turn of the rocker bolts from 0 lash to 22 lb ft. of torque.

I've seen them come apart on a couple engines with stock, torque-type rockers. But I've run them in my car for 2 seasons with Comp Pro Magnum adj rockers with zero issues.

comp says to run them cold at .011 and .04 hot. So maybe people have problems when they use a non adjustable rocker and put stock preload on them which is about.40.
