How to Identify K3 Cylinder Head

Hi All.

Can anybody tell me how you can identify a K3 front cylinder head from one off an earlier model? I have found a breaker that has a complete head but he does not know which model it is off of.

Thank you
Tim

If you look at the camchain side of the head, carby's have a bolt (same as rocker cover) that goes through the chain tunnel into the head in the centre.
The injected heads also have chambers from the exhaust ports through the rocker covers to the clean air system (carby don't have plastic takeoffs on rockers for clean air system)

Thanks for that, I'll get back to them tomorrow.
