I have seen people take that as tighten the adjuster until you collapse all the preload and make it so tight you CAN'T turn the pushrod. lol
I honestly can't understand why someone would conclude that is the right setup, given that they are working with adjustable rocker arms already so presumably they must know a little more about valvetrain than the proverbial uninitiated! lol
Still...I have no doubt this does happen, and have in fact seen numerous such on-line posts as I investigated the whole topic during my move to the hydraulic roller setup. Even those (which are Comp Cam pieces) I ended up setting up with just 1/4 turn preload.
