Cylinder Head: Notes
WARNING: This page is about a different variant/trim than selected.
The aluminum alloy cylinder heads feature cross flow type intake and exhaust ports. Valve guides and seat inserts are powdered metal. Valves are arranged in a "V", with each camshaft on center. To improve combustion speed the chambers are a compact spherical design with a squish area of approximately 30 percent of the piston top area. The cylinder heads are common to either cylinder bank by reversing the direction of installation.
