I had the same issue with my 250 six - the studs wear and rust away. Depending on how bad the studs are the washer solution may work as others have mentioned. I was lucky - I located a new manifold with perfect studs for free for my solution. These things are near imposible to drill and tap with out a press and vise - the best way to fix if the washers don't work is to remove it and take it to a machine shop like was suggested - while you're at it have the studs replaced that bolt to the intake also. You will probably have the same problem there when you take it all apart.
