The exhaust valves are 11 degrees, with a 4 degree tilt.
This cylinder head has symmetrical intake and exhaust ports and can accommodate a 2.20" diameter intake valve and a 1.65" exhaust valve.
Its nominal combustion chamber volume is 45cc, although the actual volume will depend on the seats and valves installed.
