Those holes are for the EGR system. You will notice the same holes on your lower intake manifold. Thos holes go to the center of the intake (that little hole on the top of the lower, and on the bottom of the upper). Then there is a crossover that takes the gasses to your EGR spacer.

If you have it blocked off disconect the coolent lines to the spacer because they are not needed.

I should also add that you should keep it all conected. The EGR system dosn't function at WOT so it will not cause you a hp loss.
