This is one of the better castings of the open chamber 76cc "smog heads". With full porting, larger valves and deck milling they can be made to work pretty good for a mild street perf motor to about 400hp +/- Not as good as the old "Fuelie" "Camel Back" head. (186,492,370,414)
The old fuelie heads have a much better chamber shape.
(better swirl, flame burn etc) {make a lot more torque}
Other simular 76cc "smog" castings are 336,487(X),441X,920,882
The "X" heads had a little bigger intake port.
882's are the worst of the bunch (real poor exhaust port)
