Cylinder Head Assembly: Description and Operation

HEAD ASSEMBLY
The aluminum cylinder heads have individual intake and exhaust ports for each cylinder. Valve guides are pressed in, and roller rocker arms are located on a pedestal in a slot in the cylinder head and are retained on individual threaded bolts.

Valve Train
A roller rocker type valve train is used. Motion is transmitted from the camshaft through the hydraulic roller lifter and the pushrod to the roller rocker arm.
