Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: When the cylinder head is removed, a new spacer plate gasket must be installed. Refer to Disassembly and Assembly, "Spacer Plate - Remove and Install".
Ensure that the surface of the cylinder head is clean and dry. Install a new dry cylinder head gasket onto the cylinder block.

Install pushrods (4). Make sure that the pushrods are installed in the original location and that the pushrods are seated correctly in the valve lifters.
Loosen the adjusting screws on rocker arms (5) for valve clearance. This will prevent a bent valve or a broken pushrod during installation.
Install a new O-ring seal in the rear rocker arm support.
Apply clean engine oil to all the rocker shaft bolts except bolt (25). Refer to illustration 5.
Put rocker shaft assembly (5) in position on the cylinder head. Make sure that the dowels in the rocker shaft supports are aligned with the dowel holes in the cylinder head.
Ensure that the rocker arms are aligned with the pushrods and install the rocker shaft mounting bolts. Tighten the rocker shaft mounting bolts finger tight.

3306B torque sequence
Tighten the cylinder head bolts by hand, as follows:
Tighten all the bolts (1 through 26) in the numerical sequence to a torque of 150 15 N m (115 12 lb ft).
Tighten all the bolts (1 through 26) in the numerical sequence to a torque of 250 17 N m (185 13 lb ft).
Tighten all the bolts (1 through 26) again in the numerical sequence to a final torque of 250 17 N m (185 13 lb ft).
Tighten all the remaining bolts (A through G) to a torque of 43 7 N m (32 5 lb ft).
Adjust the inlet valve lash to 0.38 mm (.015 inch) and the exhaust valve lash to 0.64 mm (.025 inch). Tighten the locknuts for the adjusting screws to a torque of 29 7 N m (22 5 lb ft). Refer to the Testing and Adjusting, "Air Inlet and Exhaust System" topic for additional information on valve lash adjustments.
