Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean the mating surfaces of the cylinder head and the cylinder block.
Clean all 26 head bolt holes on the cylinder block with Tooling (C) .
After cleaning the threads, remove any debris from the head bolt holes on the cylinder block with a vacuum hose.
Visually inspect the head bolt holes on the cylinder block for thread damage.
If a damaged head bolt thread is observed, repair the damaged head bolt thread with a Heli-Coil thread repair kit.
Inspect the cylinder head and the cylinder block for flatness. Refer to Guideline for Reusable Parts and Salvage Operations, SEBF8162, "Procedure to Measure and Salvage Cylinder Head Assemblies and Related Components".
Install the correct cylinder head gasket on the cylinder block.Note: To avoid damage to the cylinder head gasket, use guide bolts of an appropriate size to install the cylinder head.
Attach Tooling (A) and a suitable lifting device to the cylinder head. The weight of the cylinder head is approximately 184 kg (405 lb).

View A-ANote: Lubricate the bores for the cup plugs with Tooling (D) prior to installing the cup plugs. The cup plugs are measured from the head face to the top edge of the plug.
Install the cup plugs to a depth (23) of 1.25 0.25 mm (0.049 0.010 inch).Note: The minimum permissible thickness of cylinder head should be the following value 104.35 mm (4.108 inch). The flatness of the cylinder head should be within 0.15 mm (0.006 inch). The flatness should also be a maximum of 0.05 mm (0.002 inch) for any 150.00 mm (5.906 inch) span.
