Here is a link to my build thread where I replace my engine after the previous owner blew it up. There are some good pics of my new engine here that might help you out:

with those pictures there is no way any tubes could even attach to that hole, the Ignition Coil would be in the way. It has to be a freeze plug or something similar but I cant find any thing online on where to get one or what kind of plug/connector it could even be?? Grr, if only I had my old head, I could just compare the two.
