Simon, Try some hydraulic pressure. Turn the engine over and see if compression will move it, or you could try grease inserted via the spark plug hole. Then try to hold the engine under compression for a time. Penetrating oil down the studs would help too. It is probably just very well stuck. |

The head is almost certainly held on by corrosion around the studs. Try using a proper penetrating oil (plus gas) rather than WD40 and leave it for a week or two before having another go. They can be very tight. |
