Havin' a hard time imagining this one..... there is no room back of the #6 exhaust port on the manifold surfaces for ANY hole. Is this around on the back side of the head, facing the firewall?
Does this go into the valve spring area or into the water jacket or??

Here's a guess...bypass tube.
Tube for AIR.
I would look up stuff to find best way to bypass entire system, if that is what it is.

It is for air injection (emmisions). If you do not have air injection, you can install a core plug, or tap and install a threaded plug, or just bolt a plate over it (I think there is a mopar part nuber for the block off plate).
