How much of the hole depth is open in the intake manifold (1/2", 1",...)? You might be able to use a helicoil insert in the hole. http://www.emhart.com/products/helicoil.html

It would help to see some pics if you can post them, but knowing the amount of hole depth that is available for threads is important. You may not need to remove the lower intake manifold. That could be opening more of a can of worms.
