Is the EGR valve suppose to fit over the square bolt pattern with the round hole in the intake manifold ? If so, I thinking I`d just plug that hole and plug the hole on the exhaust port, wherever that is.

Yes, the 4 bolt pattern you see on the intke manifold is where the EGR goes.
I dont think i can plug it, thats where air goes into the engine lol.
I was thinking i may have to just connect it right to the intercooler.
 
If the valve acts as a pressure release valve then those can be bought and adjusted to the pressures that's desired. Sort of a universal units.
