8. Remove the 4x head stud bolts evenly by loosening off the bolts in a diagonal manner. (top left->bottom right->bottom left->top right). 
9. Remove the main cam bolt with a 10mm socket. (Caution the cam sprocket will have nothing but a gasket holding it on, remove the cover.) 
10. With the cam sprocket cover off, remove the the head to cylinder mounting bolt with a 10mm spanner. 
11. Remove the 3x cam sprocket bolts to remove the cam sprocket.
Have the engine in gear and 'crack' the bolt with a 9mm socket.
Remove the cam sprocket and let the cam chain sit in the head. 
Continues below.

12. The head is now ready to come off, a knocking hammer or a wooden handle of a hammer can be used to free the gasket from the head and cylinder surface. Once this is done slide the head up the head studs. 
There maybe oil still in then head and it may leak, keep a rag handy.
Your done!
