Abstract: A valve placement arrangement for an internal combustion engine including four intake valves and two exhaust valves per cylinder wherein the exhaust valves are disposed across the combustion chamber with ports diametrically opposed externally of the intake valves, spaced as to prevent undue heating and insure minimal thermal loading. The valve placement arrangement provides a double cross flow of intake and exhaust.
