Cylinder Head
The engine has two cylinder heads identified as the front bank (cylinders 2, 4, 6) and the rear bank (cylinders 1, 3, 5).
Each cylinder head is precision cast in a light aluminum alloy and is fastened to the cylinder block with non-reusable torque-to-yield bolts. The combustion chambers are hemispherical with four valves per cylinder and the spark plugs are located in the center. This improves the flow of gasses in the cylinders and also ensures effective combustion of the air-fuel mixture - resulting in greater efficiency.
