Metal Intake Manifold Gasket

I have a Fel-Pro upper engine gasket set that came with 2 types of intake gaskets, metal with the crossover blocked and (for lack of a better word) the fiber ones. I used the fiber ones on my last install of my cast iron intake. I want to install my Eddy Performer soon. Any problem using the metal gaskets with the aluminum intake?
