Note: There are currently two types of cylinder head bolts that are being used. The first type is a full shank design that is shown in Illustration 2. The second type is a reduced shank design that is shown in Illustration 3.
Note: Lubricate the bolt threads, the underside of the bolt heads, and the washers with 6V-4876 Lubricant prior to assembly.

(A) This is a reference dimension for the diameter of the shank of the cylinder head bolt. This bolt has a full shank diameter. ... 15.73 mm (0.619 inch)
Use the following procedure in order to tighten the cylinder head bolts with the full shank design:
- Tighten bolt (1) through bolt (26) in a numerical sequence.
Tighten the bolts to the following torque. ... 150 ± 15 N·m (110 ± 11 lb ft)
- Tighten bolt (1) through bolt (26) again in a numerical sequence.
Tighten the bolts again to the following torque. ... 150 ± 15 N·m (110 ± 11 lb ft)
- Place an index mark on bolt (1) through bolt (26). Rotate bolt (1) through bolt (26) in a numerical sequence.
Rotate the bolts in the clockwise direction. ... 90 degrees (1/4 turn)
- Loosen bolt (1) through bolt (26) until the washers are loose under the bolt heads.
- Tighten bolt (1) through bolt (26) in a numerical sequence.
Tighten the bolts to the following torque. ... 150 ± 15 N·m (110 ± 11 lb ft)
- Tighten bolt (1) through bolt (26) again in a numerical sequence.
Tighten the bolts again to the following torque. ... 150 ± 15 N·m (110 ± 11 lb ft)
- Place an index mark on bolt (1) through bolt (26). Rotate bolt (1) through bolt (26) in a numerical sequence.
Rotate the bolts in the clockwise direction. ... 90 degrees (1/4 turn)

(34) The cup plugs are measured from the head face to the top edge of the plug. Depth of installation ... 1.25 ± 0.25 mm (.049 ± .010 inch)
Height of new cylinder head ... 105.00 ± 0.15 mm (4.134 ± .006 inch)
Minimum permissible thickness of cylinder head ... 104.35 mm (4.108 inch)
Note: The flatness of the cylinder head should be within 0.15 mm (.006 inch). The flatness should also be a maximum of 0.05 mm (.002 inch) for any 150.00 mm (5.906 inch) span.
