STANDARD PROCEDURE - HEAD GASKET SELECTION
1. Measure piston protrusion for all six pistons.
2. Calculate the average piston protrusion. Maximum allowable protrusion is 0.516 mm (0.020 in.).

NOTE: There are two different head gaskets available. One gasket is for Average piston protrusion less than 0.30 mm (0.011 in.). The other gasket is for Average piston protrusion greater than 0.30 mm (0.011 in.)
