4B Edlebrock gaskets and spacer

I have a 1970 Doge Dart 340, 4Barrel. When we took the carb off to put a kit in, there was no gasket between carb. and non-metallic spacer. Do not know if there is a gasket under spacer, did not take that off. So, when using a spacer, should there be 2 gaskets, 1 above spaer, and 1 below ?
