Inspect dowels (3) for damage. If necessary, replace the dowels in the cylinder block.
Install Tooling (A) to the cylinder block. Refer to Illustration 3.
Ensure that the new cylinder head gasket (4) is the same thickness as the cylinder head gasket that was previously removed. The thickness of the cylinder head gasket is indicated by the number that is shown at Position (X). Refer to Specifications, "Cylinder Head" for more information.
Align cylinder head gasket (4) with Tooling (A) and with dowels (3). Install the cylinder head gasket onto the cylinder block.
Use a suitable lifting device to lift the cylinder head. The weight of the cylinder head is approximately 30 kg (66 lb).
Use Tooling (A) to align cylinder head (2) with the cylinder block. Install the cylinder head to the cylinder block.Note: Ensure that the cylinder head is correctly positioned onto dowels (3).
Remove Tooling (A).

Inspection of Type One cylinder head bolts
Clean Type One bolts (1). Follow Step 10.a through 10.b to inspect the Type One bolts.
Check the length of Type One bolts (1).
Use Tooling (B) to check the threads of bolts (1). Refer to Illustration 6. If any Type One bolts show visual reduction in the diameter of the thread over Length (Y), replace the bolts with a new set of Type Two bolts. If Type One bolts are replaced with a new set of Type Two bolts, refer to the installation procedure for Type Two bolts.
Install bolts (1) to cylinder head (2).
