Adjust the valves and set the fuel injector heights as follows:
1. Exhaust Valve Rocker Arm Assembly
4. Rocker Arm Shaft
2. Fuel Injector Rocker Arm Assembly
5. Cylinder Head
6. Intake Rocker Arm Assembly
Figure 3. Valve Overlap Period

Set Valves on Cylinder No.

they length is usually related to h.p. rating
with a serial number i'll be able to tell you which one you need.
