Edelbrock gaskets are .060 thick. You can buy .045 and .031 thick intake gaskets that will allow the intake to fit properly if milling has been done to the heads and or block.

the old intake had reg felpro gaskets and that intake has oblong holes and they are hogged out pretty good on both sides. I hate to ruin the $22.00 edelbrock gaskets i put on there to see but im positive that with no gasket at all the intake holes would not lineup. but i suppose im gonna have to try it and see.
