The main difference will be the size of the ports. The bigger the ports, the better the airflow, thus increasing power. The difference between my two heads above is that one has bronze valve guides, and the ports are slightly bigger. Plus the valves are slightly bigger than a stage 3.
On your 1275, with stage 1 kit ( I presume K&N, Alloy Inlet manifold, LCB and 2" exhaust ???) then fitting the stage 4 head would certainly give you a very healthy power increase when set up on a rolling road to increase fueling and alter ignition timing to suit your engine. Fitting a "lumpier" cam would further release potential from the head by opening the valves further and leaving them open for longer. This would require the engine to be removed but is not nessisary at your state of tune. So yes, it would be fine on your 1275!
Hope this helps.
