Abstract
A cylinder head assembly in which the two cylinders of a V-twin configuration are arranged in a V with the cylinder provided on a plane which is transverse to the crankshaft of an internal combustion engine and normal thereto. Each of the cylinders is assembled together with an interlocking interference fit for installation on a common crankcase to permit larger engine displacements within the given physical dimensional space of the engine.
