Turn the motor so the cam lobe is pointing away from the rocker arm and stick a feeler gauge in between the lobe and the rocker. Should be.006" on intakes and.010" for exhausts. Do them one at a time and rotate motor to position the lobes properly as you do each one. Loosen nut and turn screw on the rocker to make adjustments.
