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:
- Tighten for bolt 1 through bolt 14 in a numerical sequence to 270 ± 25 N·m (200 ± 18 lb ft).
- Again, tighten the bolt 1 through bolt 14 in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Finally tighten 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.
- Tighten the bolt 15 through bolt 26 in a numerical sequence to 270 ± 25 N·m (200 ± 18 lb ft).
- Again, tighten the bolt 15 through bolt 26 in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Finally tighten the bolt 15 through bolt 26 in a numerical sequence to 450 ± 20 N·m (330 ± 15 lb ft).
- Tighten the bolt 27 through bolt 39 in a numerical sequence to 47 ± 7 N·m (35 ± 5 lb ft).
Note: Tighten the bolt 27 through bolt 39 only after the cylinder head bolts have been given final torque.
(1) Torque for the taperlock studs ... 35 ± 5 N·m (26 ± 4 lb ft)

If equipped, use the following procedure in order to tighten the bracket for the fuel pump and the bracket for the timing cover to the cylinder heads.
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.
(2) Use the following procedure to tighten the bolts:
- Position the fuel pump brackets over the bolt holes that are in the cylinder head. Install the cylinder head bolts (3) through the bracket. Finger tighten the bolts.
- Remove the two bolts from the fuel pump in order to install the bolts (2) .
- Align the fuel pump against the fuel pump brackets and install the bolts 2. Tighten the bolts to the standard torque.
- Tighten the bolts (3) to 44 ± 7 N·m (32 ± 5 lb ft).

Note: Apply liquid soap (40% solid) to the O-ring seal (7) and to the bore of the cylinder head prior to installation of the nozzle adapter.
Note: Apply 4C-5599 Anti-Seize Compound onto the threads of the nozzle adapter prior to installation.
(6) Tighten the nozzle adapter to the following torque. ... 200 ± 14 N·m (150 ± 10 lb ft)
