Removing the head

You need patience, and the firm belief that it will come off.

Also - check the forum, this has been covered before.

Amongst other things, you can put (say) a tyre lever on a head stud, hook it under a spark plug lug, and push the other end down to get some lift.

Repeat, using different studs and plugs.   I think it took an hour or so before movement was detectable.

As soon as you get any movement at all, you know it will come off sooner or later.

You may have to sacrifice a plug to get enough of a lug to get your lever underneath.

Good luck.
