AnswerINSTALLATION
Clean all surfaces of cylinder block and cylinder heads.
Install new gaskets on cylinder block Head Gasket Installation
The Cylinder head bolts are torqued using the torque yield method, they should be examined BEFORE reuse. If the threads are necked down, the bolts should be replaced Checking Bolts for Stretching (Necking)
Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale the bolt should be replaced.
Tighten the cylinder head bolts 1 thru 8 in the sequence shown in Cylinder Head Bolts Location and Tightening Sequence Using the 4 step torque turn method, tighten according to the following values:
First-All to 61 N·m (45 ft. lbs.)
Second-All to 88 N·m (65 ft. lbs.)
Third-All (again) to 88 N·m (65 ft. lbs.)
Fourth-Turn an additional 1/4 Turn. (Do not use a torque wrench for this step.)
NOTE: Bolt torque after 1/4 turn should be over 122 N·m (90 ft. lbs.) If not, replace the bolt.
Tighten head bolt number 9 Cylinder Head Bolts Location and Tightening Sequence to 33 N·m (25 ft. lbs.) after head bolts 1 thru 8 have been tighten to specifications.
Inspect push rods and replace worn or bent rods.
Install push rods, rocker arm and shaft assemblies with the stamped steel retainers in the four positions, tighten to 28 N·m (250 in. lbs.) Rocker Arm Shaft Retainers
Place new cylinder head cover gaskets in position and install cylinder head covers. Tighten to 12 N·m (105 in. lbs.)
