Cylinder Head Assembly: Description and Operation

Cylinder head
The aluminum cylinder heads have individual intake and exhaust ports for each cylinder. Valve guides are integral, and rocker arms are retained on individual threaded studs.


Valve Train
A very simple ball-pivot and rocker type valve train is used. Motion is transmitted from the camshaft through the hydraulic lifter and pushrod to the rocker arm. The rocker arm pivots on its ball and transmits the camshaft motion to the valve. The rocker arm ball locates on a stud, threaded into the head, and is retained by a nut. The pushrod is located by a guide plate held under the rocker arm stud, assuring that the rocker arm operates in the plane of the valve.
