Dazza thats the H75 head more commen on the "econamy" a14's. most a15's came with the H89 witch has the same chambers but larger valves then the GX head. The advantage of a GX head is the aproach angle and lack of a water galery over the intake ports.

I think in a street going 1000 this motor will still move it along quite nicely!
