I've done a search but could not find anything specific from past posts. Maybe you guys can help me out ...

I have a 1995 C36 and would like to get the valve cover powder coated. This means that I have to remove the valve cover while it gets sand-blasted and powder coated (2-day procedure).
Here's my "novice" question:
How do I remove the valve cover? What do I watch out for?
Do I have to replace any seals or gaskets while I'm doing this?
Should I even attempt it?
Thanks for any input
