              It is possible for inlet and exhaust ports to be on the same or opposite sides
            of the cylinder head, known as precross-fl ow or cross-fl ow. In addition, two
            cylinders can share a common inlet port and this is known as a siamese port.
            When a single inlet for each port is used, this is known as parallel ports.
