OK, so I took of the fuel pump and the upper bolt (the one you guys are talking about) and sprayed some lube in the hole, just to make sure it was the same oil galley and yep it ran out the fuel pump mounting hole. The bolt seemed short enough and I didnt see any damage to it but.... the fuel pump push rod seems to be stuck. Tapped it a few times wouldnt budge so I took some vise grips and tried to turn it and pull it out, wont budge. Should I crank the engine a couple of times and see if that pushes it out? Kinda hard to see how the push rod could get bent?

Sounds to me like your fuel pump rod is bent, binding in the hole. I would lock a pair of vice grips on it and either lever it out or rig some sort of slide hammer to get it out. I'd be very concerned that the lobe on the cam may be toast, and I also wonder how it moved enough to work the mechanical pump if it's stuck that tight? This may be the start of a very bad day for you, my friend. If you're very, very lucky the old rod will come out and a new rod will work just fine. Once you get it out chuck it into a drill press to see if it runs true....
