Intake Leak

I'm working on a Magnum iron head with a Mopar M1 aluminum intake.
When I took it apart last weekend there was oil in the intake ports of the head. You can trace the leak back between the gasket and the head.
I could see the crush on the old gaskets and the intake is only about an 1/8th. of an inch below the intake port.
the head has a dip down flat spot right below the intake ports, but the manifold is straight across. That is why I was thinking to have the intake tig welded and then milled to match the heads profile, by doing this it will create about 1/4 of an inch of manifold surface to clamp the gasket. If that makes any sense to anybody.
I would take pictures but my camera is broken.
