Different lifters require different pre load. What lifters do you have?

Use a .100" shorter push rod (flat tappet cam) then tighten the adjuster while bouncing the push rod up and down until it has no more clearance, then tighten an additional 1/2-3/4 turn. Tighten the jam nut whil holding the allen adjuster from turning. Done.
