      Put all 16 push rods in the holes with the rocker arms on top.


      Turn the engine to top dead center. Number 1 piston will be up and the exhaust and intake lifters will be down. Adjust the exhaust valves 1-3-4-8 and the intake valves 1-2-5-7 to specs.


      Turn the engine one complete revolution, then adjust the exhaust valves 2-5-6-7 and the intake valves 3-4-6-8 to specs.


      Turn the rocker arm nut down until you can turn the push rods with your fingers to what is called the zero position. Turn the rocker arm nut an additional half turn.


      Start the engine to make sure there are no rattles. With the engine running, you can turn the rocker arm nuts down an additional quarter turn.
