Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean the gasket surfaces of the cylinder head and the cylinder block. Do not damage the gasket surfaces of the cylinder head or the cylinder block. Ensure that no debris enters the cylinder bores, the coolant passages, or the lubricant passages.
Inspect the gasket surface of the cylinder head for distortion. Refer to Specifications, "Cylinder Head" for more information.
Refer to Systems Operation Testing and Adjusting, "Piston Height - Inspect" for the correct method to identify the head gasket thickness required.
Refer to Specifications, "Piston Rings" for the piston height range and cylinder head gasket requirements.

Typical example
Inspect dowel (5) and dowel (6) for damage. If necessary, replace the dowels in the cylinder block.
Install Tooling (D) to the cylinder block. Refer to Illustration 1.
Align cylinder head gasket (4) with Tooling (D) and with dowel (5) and dowel (6). 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). Note: Use a spreader bar during the lifting operation in order to distribute the weight of the cylinder head.
Use Tooling (D) to align cylinder head (3) with the cylinder block. Install the cylinder head to the cylinder block. Note: Ensure that the cylinder head is correctly positioned onto dowels.
