### Installation Procedure

1. Install the cylinder head gasket.
2. Install the cylinder head.

Notice: Refer to Fastener Notice in the Preface section.

Notice: This component uses torque-to-yield bolts. When servicing this component do not reuse the bolts, New torque-to-yield bolts must be installed. Reusing used torque-to-yield bolts will not provide proper bolt torque and clamp load. Failure to install NEW torque-to-yield bolts may lead to engine damage.

3. Install the NEW cylinder head bolts.

Tighten
Tighten the cylinder head bolts in sequence to 60 N·m (44 lb ft). Turn the bolts an additional 95 degrees using the J 36660-A .

4. Install the engine left side exhaust manifold. Refer to Exhaust Manifold Installation .
5. Install the engine left side spark plugs. Refer to Spark Plug Replacement .
6. Install the engine left side spark plug wires to the spark plugs. Refer to Spark Plug Wire Harness Replacement .
7. Install the oil level indicator tube. Refer to Oil Level Indicator and Tube Replacement .
8. Install the right engine mount strut bracket. Refer to Engine Mount Strut Bracket Replacement .
9. Remove the thermostat bypass pipe. Refer to Thermostat Bypass Pipes Replacement .
10. Install the exhaust crossover pipe. Refer to Exhaust Crossover Installation .
11. Install the valve rocker arms and pushrods. Refer to Valve Rocker Arm and Push Rod Installation .
12. Install the lower intake manifold. Refer to Intake Manifold Replacement .
13. Install the upper intake manifold. Refer to Intake Manifold Replacement .
