Manifold doesn't line up

that looks like a good sized gap for an intake gasket to seal. I can see that being a problem when tightening down the intake, it may even crack it. no milling any where is going to fix it, it will only make it worse. it looks like it would take doubling up on gaskets to seal it. I would compare measurements between the two intakes just to see how far off they are from each other.
