Note: Use clean engine oil to lubricate the threads of the cylinder head bolts before assembly.
Use the following procedure to tighten the cylinder head bolts:
- Torque for bolt (1) through bolt (14) in a numerical sequence to 270 ± 27 N·m (200 ± 20 lb ft)
- Again torque the bolt (1) through bolt (14) in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Finally torque the bolt (1) through bolt (14) in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Install the rocker arm assemblies onto the cylinder head.
- Torque the bolt (15) through bolt (18) in a numerical sequence to 270 ± 27 N·m (200 ± 20 lb ft).
- Again torque the bolt (15) through bolt (18) in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Finally torque the bolt (15) through bolt (18) in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Torque for bolt (19) through bolt (27) at any tightening sequence to 43 ± 7 N·m (32 ± 5 lb ft)
Note: Tighten the bolt (19) through bolt (27) only after the cylinder head bolts have been given final torque.

Note: Apply liquid soap (40% solid) to the O-ring seal (29) and to the bore of the cylinder head prior to installation of the adapter.
Note: Apply 4C-5599 Anti-Seize Compound onto the threads of the adapter prior to installation.
(28) Torque for adapter ... 95 ± 7 N·m (70 ± 5 lb ft)

Note: Use clean engine oil to lubricate the threads of the bolts prior to installation.
Note: Tighten the bolts only after the cylinder head bolts have been given final torque.
(30) Use the following procedure to tighten the bolts:
- Position the housing support over the bolt holes that are in the cylinder head. Install the bolts (30) through the supports. Finger tighten the bolts.
- Install the timing gear housing to the supports and tighten the bolts.
- Torque the bolts (30) to 43 ± 7 N·m (32 ± 5 lb ft).
Note: Use 6V-6640 Sealant on the cup plugs.
(F) Install the cup plugs in the front and rear side of each cylinder head to the following distance. ... 2.5 ± 0.8 mm (0.10 ± 0.03 inch)
Note: Do not install cup plugs in rear side of each cylinder head for the engine arrangement with the water cooled manifolds.
(G) Install the cup plugs in the rear side of each cylinder head to the following distance. ... 4.3 ± 0.8 mm (0.17 ± 0.03 inch)
