A bit of a pain you couldn't get the bits for when we were initially going to do it really Paul, I've just had a look and my schedule is manic. I'm on nights until Wednesday morning, and wednesday I'm putting a Corsa engine back together. Thursday and Friday I'm in brackley helping Jaime with the Rover, and then Sat/Sun/Mon I'm on night shifts again, so getting down to bristol is looking like it's going to be about 10 days away!
If you're confident, maybe you should have a go yourself if you need the car for Monday, it's really an easy job to do! As others have said, 2 torx bolts up the side of the RH head, and it comes off. You may find it a bit fiddly around the air injection pipe, but it's do-able.
Post up if you get any probs, and if you're really stuck we'll still arrange a time to sort you out!
Cheers
James
