Tighten it down with both valves closed for that cylindert while rotating the pushrod with your fingers. When you feel resistance, give it 1/4 to 3/4 (depending on who you believe) more of a turn. This slight added amount is supposed to put the hydraulic piston of the lifter in the middle of it's travel where it can adjust for thermal contraction and expansion and wear of the valve train components. It should maintain 0 clearances in the valve train.
