If it's an A+ then almost certainly a 1275. The 948 head would fit but would need the stub that normally connects to the water pump blanking off (that's if you current head is an AS+ and sans stub) The engine would be down on performance as the 948 head has smaller valves and a larger chamber volume so a lower compression ratio. It could be made to work with some work on the ports and a skim but better to find the right head to match the engine ie a 12G940.
