Cylinder Heads
The cylinder heads are unique to each cylinder bank and are attached with deep seated bolts, to the cylinder block. Two
hollow dowels align each cylinder head with the cylinder block.
Each cylinder head gasket has a silicon beaded compos ite gasket with metal eyelets for the cylinder bores.
There are two overhead camshafts that operate four valves each cylinder with solid aluminium-alloy valve lifters. A steel
shim in the top of each lifter gives adjustment of the valve clearances.
Collets, valve collars and spring seats locate the valve springs on the intake and exhaust valves. Valve stem seals are part
of the spring seats.
Four 14mm diameter spark plugs are installed in recesses on the center-line of each cylinder head.
Inlet/Exhaust Manifolds
Intake air is filtered and passed through Mass Air Flow (MAF) meters. The air then passes through the throttle body into
the eight-branch inlet manifold.
