Intake gasket Help

Okay, so i have a 318 that I am swapping a 4bbl intake and carb onto. I have a set of gaskets from my brothers rebuild kit for the motor, but wasnt sure whether or not to use them. They are the metal ones for where the intake meets the head, and cork for the front and back of the intake.

I didnt know whether to use them, or if I should just use some RTV silicone to seal it all up..

Give me your guys opinions on what to do..
