Is the inside diameter of the outboard holes (where they mate with the heads) 1.650" or 1.750" ?? Thank you!
I believe you are referring to the two threaded holes on the outside base of the manifold. They are neither size you provided. These holes have an ID of .250 (6.35mm) when measured to the outside edge of the threads. The center-to-center measurement of these holes is approximately 3.0 inches.

I am switching my CV 40 carb out for a Mikuni HSR45 carb on my 2000 Dyna Lowrider. Will this work on my bike? Will it bolt up to my heads?
If your existing manifold has a MAP sensor hole, this is the correct replacement. If it does not, you will either need the version without the hole, or you will need to plug the hole. You will also need a flange adapter. I have posted some links below for more information:
