The factory specification is to tighten the adjusting screw one turn after all the free play is taken out. I've had better luck doing 3/4 turn instead. After the preloaded lifter sits for a few minutes, the inner plunger leaks down slowly to allow the valve to close fully, so once you get all 12 valves adjusted, go have a cold one or two to let everything normalize!
