Cylinder Head Assembly: Description and Operation

GENERAL INFORMATION
Cylinder heads are designed to create high flow combustion chambers to improve performance, while minimizing the change to the burn rate of the chamber. Valve seat and guides are inserts. A steel flanged composition 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.
