Rocker arm pedestal bolts are 20 ft lbs, Injector hold down bolts are 120 in lbs.

MAKE SURE that your bolt holes are free of rust and debris, clean them out with a bottoming tap and blast them with lots of compressed air or be sorry.


Lightly lubricate the cylinder head retaining bolt threads and flanges with clean engine oil and install the cylinder head retaining bolts.
Tighten the bolts in the sequences shown in three stages.


CAUTION: Do not use too much engine oil on the threads of the cylinder head bolts, or damage to the threads and poor sealing can result. Do not use anti-seize compounds, grease or any other lubricants except engine oil on the cylinder head bolt threads because they will affect the true torque valve reading of the bolts.
