Cylinder Heads

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

The cylinder heads 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. The valve rocker arm covers are retained to the cylinder head by 4 center mounted rocker arm cover bolts. RPO LY6, L76 and L9H use a high-flow cylinder head with an offset intake valve rocker arm design.
