Cylinder Head Assembly: Description and Operation

HEAD
Cylinder heads incorporate valve shrouding to create turbulence-producing combustion chambers, described as fast burn. Valve seat and guises are inserts. A steel flanged compostion type gasket is used between head and block.

VALVE TRAIN
Valve train design incorporates the use of hydraulic roller tappets. Rocker arms are installed on a rocker arm shaft attached to the cylinder head with four bolts and retainers. Viton valve stem seals provide valve sealing. Conventional type pushrods, retainers and valve stem locks are used. Unique beehive style valve spring are used with lightweight retainers for improved high RPM performance.
