HI

Torque hold down bolts at 12 to 14 ft lbs,

valve set

The set marks are A or 1-6VS, B or 2-5VS, and C or 3-4VS. There is also a 1-6TC mark.
Injector is always set first then valves. You can start anywhere in the sequence and required two revolutions of the engine to complete all adjustments

turn accessory drive pulley until one of the marks lines up with the pointer, say A or 1-6VS, check to see which set of rocker levers are loose (1 or 6) this is the cylinder to be adjusted.

adjust the injector to 72 inch-lb, once set lock with locknut.
Adjust valves on the same cylinder to 0.014" for the inlet and 0.027" for the exhaust.
Turn engine to next VS mark and adjust the next cylinder following the firing order (ie 2 or 5

firing order is 1-5-3-6-2-4.
