52 Carl has the right solution when it comes to getting the manifolds mated up and secure so both manifolds get machined at the same time.
The one big potential exhaust leak that this won't fix is the really uneven surface on the heat exchange box where it mates up to the exhaust manifold (picture 1 - mostly upper left corner area).
That surface is just too uneven to allow a gasket to prevent exhaust leaking, especially at the top left corner in the picture. It either needs to be cleaned up to allow good gasket seating (don't forget to check the corresponding surface on the exhaust manifold) or filled/leveled to create a better sealing surface. Changes in this surface area shouldn't be enough to cause misalignment of the manifold to head ports, if not too drastic.
Otherwise, you may want to see about finding another intake manifold (and exhaust manifold depending on what condition problems you may find there).
Am sure others will chime in here on possible solutions/options.
