So now you're pretty much ready to start removing the cam gears.
The first thing to do is to remove the no.1 bearing caps. There's 4 bolts that you'll need a 10mm socket for. Undo them uniformly, and remove the bearing caps. If the caps are difficult to remove you can prise them with a flat bladed screwdriver. Again wrap the tip in tape so as not to scratch the head. Keep the individual caps and their bolts together so you're not mixing up bolts and caps.
Now remove the oil seal

Here's a shot of one of the no.1 bearing caps once removed:-
And of the cams:-
So now you need to undo the remaining caps. These need to be done in order. I've got a paper-copy of the order to remove them in which I'll try to scan in. In the mean time, if you look closely at the top of the remaining caps, you'll see they have numbers. 2-7.
You need to undo them in the following order in a number of passes.
2-6-4-5-7-3
Loosen the inner of the two bolts before loosening the outers. I did mine over 3 passes. As I was undoing them there was a little "clunk" as the springs under comrpression released.
No caps:-
Again keep the individual caps and their bolts together (sandwich bags are ideal) Don't worry too much about labelling them as they're stamped with their number on top, along with and arrow that points towards the front of the engine.
You should now be able to lift out the cams:-
I couldn't find any particular marking on each cam, so I labelled them as I removed them:-
But don't worry too much as only the exhaust cam has this larger diameter part to it:-
And here's what it will look like with no cams:-
