Cleaning and Inspection

CLEANING
Thoroughly clean the engine cylinder head and cylinder block mating surfaces. Clean the intake and engine exhaust manifold and engine cylinder head mating surfaces. Remove all gasket material and carbon.
Check to ensure that no coolant or foreign material has fallen into the tappet bore area.
Remove the carbon deposits from the combustion chambers and top of the pistons.

INSPECTION
Use a straightedge and feeler gauge to check the flatness of the engine cylinder head and block mating surfaces.
