Those would be a No Brainer for me. Deep port the flanges of the performer intake to match a set of 1243 Fel-Pro gaskets

That's almost exactly what I did, but I made templates of the ports instead of using a gasket. It was a cheap manifold I had on hand, so I used it, while understanding it's not much (if any) better than a factory cast-iron one. Chances are good I'll swap it out for a Weiand 8002 I've got on the shelf.
