You can get too big on primary size, unless you have the engine for the 1 7/8 you will be fine with the 1 3/4. On a stock engine You could possibly lose and I dont think you would see any increase IMO, Now ported heads and a fast intake with a stout cam and the larger ones are the way to go.

Either of the two. There isnt much difference although people will tell you other wise based on what brand they have.
