a gx head consists of
heart shaped combustion chambers
oval ports (like the standard A15 cylinder head). Standard A12s have smaller round ports. The best heads have the ports up higher than the round-port version. There are Oval port heads with the ports lower down.
double valve springs
valves. Compare to A14/A15 with 37 mm inlets & 30 mm exhaust valves
Later GX heads have two little water jackets under the ports, for warming the inlet manifold
intake ports shaped differently for flow and swirl
and twin sus strapped to the side of it
