I turned the pushrods with my finger and slowly tightened the adjusters until i felt resistance, then tightened 2.5 turns for .08 the first time and 1.25 turns for .04 the second.





With many lifters it is very difficult to "feel" when you are at zero preload. It takes awhile to acquire the feel, and it is best to do it while watching the lifter to verify the results.

With the lifter on the base circle and the rocker adjustment sloppy loose, put the allen wrench in the adjuster and with it between your thumb and index finger turn slowly with no downward force and don't turn or even touch the pushrod. When you meet the slightest resistance, you're probably at zero. Adjust from there.

I think that others have said that the aluminum rockers are a little noiser than the steel ones on fast rate cam. I don't know this to be true.
