If not you can drill it for a helicoil if you don't need a lot of torque on it. And then lather the bolt up with silicone to prevent a vacuum leak. Let the silicone dry before you fire.
Otherwise drill and tap bigger, be careful if you're drilling into a head. Don't go too deep or too big or you'll make yourself another manifold vacuum port, or a sweet exhaust leak, or an even sweeter coolant jet.

The helicoil is the answer. What happened originally was that one of the long bolts that holds the upper and lower intakes together snapped because it was a cheap bolt. I drilled down into the center of the broken peice and used an easy out to remove it. We never touched the threads so something else must have happened. Mike, do you want to fess up what you did?
Anyways, most part stores sell helicoil kits. You'll need to pull the upper intake off and then drill the hole to the appropriate size for the heilcoil. The kit will also come with a tool to install it and I beleive it comes with loctite.
