Two Different Intake Gaskets in 8ba BEST Gasket Kit

[Shoebox]

Buttoning up the 276 8ba going into my '51 Tudor project, I have 2 intake gaskets in my Best Gasket kit. One is the common grey paper and the other is black, with a thin metal sandwiched in the middle. Set on top of one another, they are a perfect match. Following the old adage, "the dumbest question is the one you don't ask", which one should I use?


I was going to do a sexy trim of the paper gasket and masking prior to painting, to follow the intake lines, but if there is a benefit/need to use the sandwich gasket,..... well, that's going on as is. Thanks guys, going back into the 95 degree shop to get something done.
