Having to change my manifold as it as a crack in it

and i'm not looking forward to it really but needs must.
Going to leave the turbo were it is and just get the manifold off on its own.
Ive got my mani and turbo gaskets sorted and the wd40 ready.
Had some expert advice off Shaun again as usual

but Any more tips welcome.
Wish me luck as I've never had to do it before
