Disclosed is a rotating cylinder head for use on a barrel type engine. The cylinder head rotates about the central axis of the engine driven by the main drive shaft. The cylinder head contains an intake port and exhaust port. As the cylinder head rotates, it is timed so that the intake port and the exhaust port become positioned over a pre-selected pair of cylinders which are in respective intake and exhaust cycles. In this manner, the cylinder head functions as a valve assembly. This type of rotary valve is advantageous because it allows the engine to operate at speeds limited only by the piston assembly and not limited by the poppet valve assembly found on more conventional internal combustion engines.
