Cylinder Heads

WARNING: This page is about a different variant/trim than selected.

The cylinder head assemblies are cast aluminum and have pressed in place powdered metal valve guides and valve seats. Passages for the engine coolant air bleed system are at the front of each cylinder head. There are no exhaust gas passages within the cylinder head. Valve rocker arm covers are retained to the cylinder heads by four center mounted rocker arm cover bolts.
