Have the flanges of the intake manifold "surfaced".

You might even be able to do it yourself if you have access to a flat surface and some sandpaper. If you look up on youtube DIY techniques of surfacing warped heads, you get an idea of how you can achieve this with your intake manifold.

If multiple gaskets leak it sounds like there is a problem with the surface(s) you're trying to seal. I think the likelihood would be with the intake manifold which would also be a bit easier to check or get to a machine shop if you need to.
