I think that you could install the jack and king studs on one side, put the header up, and attach it in several spots to the cap plate, as best as possible as it would be leaning down at the other end, use a 4x4 under the other end of the header on top of the jack and then jack it up until you could get the studs underneath at the other end.
Just a thought have not done it before, good luck
