Description of Change: The rocker support assembly has a new pushrod retaining feature in the design. This change makes the new rocker support assembly more robust than the previous rocker support.
The design of the rocker shaft has been changed to increase the length of the dowel holes with added chamfer. The longer dowels engage in the support assembly to improve assembly alignment.
The rocker arm button for both the exhaust rocker arm and the intake rocker arm has an increased interference fit. The interference fit improves retention of the button on the rocker arm insert.
