Basically, make sure the pushrod is on the base-circle of the cam...not the lobe.
When the pushrod is about to push in the lifter spring (or when you cannot turn pushrod by hand anymore), you're at zero-preload on the lifter...stop and give about 1/2 turn more (or around .020"). Tighten the lock-nut & then put a little-more snug on the rocker nut again...This assures the locknut is in tension on the stud...will not back off.
