rocker adjustment
Hello,

what is the correct preload to adjust rockers with :

* LS7 (#12499225) lifters
* 7/16 Comp CAms Ultra Pro Magnum (#1605) ?

I'd start with a 1/2 turn and see how it goes.

hello Shoebox,

that's what i've done and it seems ok. just wanted to be sure because of the new lifters.
The valvetrain seems a bit noisy with these new rockers too

Pro/Ultra Pro Magnums aren't known to be the quietest around. It's not a performance issue, though.
