Changing out the water pump on my 1992 460.

Questions:

1. Is it recommended to also remove the aluminum cover behind the water pump and replace its gasket?

2. What all is involved in replacing the cover gasket? I know there is a paper/fiber gasket similar to water pump gasket, but are there other gaskets behind cover that will also need to be replaced? Is this opening a can of worms?

Currently, these parts are not leaking. I am replacing water pump, as I am replacing the radiator and figure it wouldn't hurt to have a new water pump in there.

Thanks
