Manifold Removal, Easy or Hard? And Turbo Clocking?

[bigcheez2k3]

Due to some complications I may end up fitting the TD04 myself. I'll need to go get some adaptor plates made up so will need to remove the exhaust manifold to take it to a guy I know.

Thing I'm worried about is snapping a stud, how likely is this? This is why I was going to take it to Kris as he has more experience with this but it's taken long enough already and I need to get back to work.

Will do the intake manifold too as I have a gasket that covers them both.

Also, I know the turbo needs to be clocked. This involves undoing the clamp then what? Really don't want to mess that up either.
