Cylinder heads are unique to each cylinder bank and are
secured, using deep seated bolts, to the cylinder block. Two
hollow dowels align each cylinder head with the cylinder
block.
Each cylinder head gasket consists of a silicon beaded
composite gasket with metal eyelets for the cylinder bores.
Each cylinder head incorporates dual overhead camshafts
operating four valves per cylinder via solid aluminium-alloy
valve lifters. A steel shim in the top of each lifter allows
adjustment of valve clearances.
Collets, valve collars and spring seats locate the valve springs
on the intake and exhaust valves. Valve stem seals are
integrated into the spring seats.
Four 14mm spark plugs are located in a recess on the center-
line of each cylinder head.
