Intake install help- pic

I’m putting an Edelbrock Performer intake on my 318. I read that I shouldn’t use a metal type gasket with an aluminum intake. All the performance gaskets that I’ve seen don’t have the center port cut out of them. Why is that? Do I need to cut the port out? See in the picture below that the stock metal gasket has the port cut out, but the performance gasket does not.

Thanks,
Kris
