but you'll need the proper injector height pin to do the injectors,thats why i need the engine serial number.
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
Cylinder with Valve Overlap
Set Valves on Cylinder No.
Set Injector Height on Cylinder No.
Never set the valves and injector of the same cylinder at the same time. Doing this will result in engine damage.
1. Intake Valve
2. Valve Button
5. Feeler Gage
3. Intake Rocker Arm Assembly
6. Tip of Intake Valve

follow the sequence,overlap on 6,valves on 1 and injector on 5 and so on ..
i do believe there are 4 or 5 injector height tools
they length is usually related to h.p. rating
with a serial number i'll be able to tell you which one you need.
