should I cover valves while cleaning valve cover?

I just bought a valver cover gasket, and when I took off the cover (of course it is made of plastic I found out) I was wondering if I should cover the valves while I clean all the crap around it. Any ideas what to use. Or not at all. Also should I buy a new valve cover to replace the original one. Is the old plastic cover fine enoght to use? I'm just using it for around town and camping. No rock climbing or anything. It is ony held on by two bolts on the top of the cover, (jeep saving money that year I guess) but I think it is threaded along the side of the block for a cover that will bolt down the side like everyone else in the world.... First time doing this so help is needed

You don't want old gasket remnants floating around inside your head, so do whatever is necessary to prevent that.

The plastic factory valve covers are prone to leaking. That's why the vast majority of CJs that are still on the road have aftermarket aluminum covers that bolt around the perimeter.

x2. I cover any holes that would let gasket material drop down inside the engine. Used a razor blade to scrape off residue carefully and then wipe the sealing surface with something like acetone to clean the metal surface.
