Clean all sealing surfaces of engine block and cylinder heads. (Refer to 9 - ENGINE - STANDARD PROCEDURE) Position new gasket(s) on engine block . The left bank gasket is identified with the “L” stamped in the exposed area of the gasket located at front of engine (shown in ). The right bank gasket is identified with a “R” stamped in the exposed area of the gasket also, but is located at the rear of the engine.

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 must be replaced .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 1–8 in the sequence shown in . Using the 4 step torque turn method, tighten according to the following values:Step 1: Bolts 1 – 8 to 61 N·m (45 ft. lbs.)Step 2: Bolts 1 – 8 to 88 N·m (65 ft. lbs.)Step 3: Bolts 1 – 8 (again) to 88 N·m (65 ft. lbs.)Step 4: Bolts 1 – 8 turn an additional 1/4 Turn. (Do not use a torque wrench for this step.)Bolt torque after 1/4 turn should be over 122 N·m (90 ft. lbs.). If not, replace the bolt.

Inspect and replace worn or bent push rods.Install the push rods.Install the rocker arm and shaft assemblies (2). (Refer to 9 - ENGINE/CYLINDER HEAD/ROCKER ARMS - INSTALLATION) Install the cylinder head covers. (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTALLATION).

Install the exhaust manifolds. (Refer to 9 - ENGINE/MANIFOLDS/EXHAUST MANIFOLD - INSTALLATION) Install new O-ring on oil level indicator tube. Install oil level indicator tube assembly .Install upper and lower intake manifolds. (Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANIFOLD - INSTALLATION) Fill the cooling system. (Refer to 7 - COOLING - STANDARD PROCEDURE) Connect negative cable to battery.
