NOTE: Rocker arm and shaft assembly can be installed either prior to or after (preferred) cylinder head installation.

Rotate camshaft gears to the position shown in (1, 8, 9). See Fig 1. With the camshaft gears in these positions the lobes are in a neutral position (no load to the valve). This will allow the rocker arm shaft assembly to be tightened into position with little or no valve spring load on it.
