Would you just leave the 2 barrel on it? If so would you think a Holley 2 barrel would be a improvement over the dual jet.

When I put the o2 sensor on my 283 with its stock power-pak heads, intake and 2 jet carb, the AFR readings were ideal at idle, at cruise and wide open. It was made for that engine, with that intake and those heads. I don't see a Holly 2 barrel as being an improvment myself. See the last post on this thread for the 2-jet AFR readings.
