Hey Ballbag... lol.
Yes. It is easy and straight forward to remove, (drop) the headers down an inch or two, replace gaskets. Undo the headers/up pipe flange, replace gasket there, and for a standard turbo, its moreso the securing bracket that will give you heartache. I can remove the exhaust and up pipe off mine now without removing the turbo.... but mines seen some ahhh... modifications.
