I like Flatout brand intake gaskets that have a wire mesh layer to resist boost/vac from blowing out gasket in thin areas. have had good luck with mosy any premium exh gaskets the main reason they fail is surfaces not being flat. Have seen many people get away with no exh gasket and only some high temp silicone if machined surfaces mate perfectly. If exh surfaces are questionable go with copper or Flatout offers MLS exh gaskets now. Hope this helps.
