Got the head off:

and in the process noticed that the timing was massively out:

Now I am stumped on the sump. It is held on by theses (imo stupid) hex bolts:

And I have managed to snap two hex key tools inside two of the nuts (the rest undid really easy!).
Anyone have any idea, either how to get the rest of the tool out of the bolt, or how to remove the bolt without doing any damage to the sump or block?
