I think I may have a warped intake manifold. I started the engine today and I have an audible air leak at the same location I have had three times. Three gaskets. Three times taking it apart and putting it back together again. Same location. The latest gasket was the most heavy duty I could find. Rubber coated steel and much thicker than the previous ones.

I could beat the previous owner with his own severed arm. Gahhhhh!
