Cylinder Heads
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The cylinder head assemblies are cast aluminum and have pressed in place powdered metal valve guides and valve seats. Passages for the vapor ventilation 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 head by 4 center mounted rocker arm cover bolts.
