Hello. Power Valve question.

Everything is working fine, still very rich on idle. Silly me... I finally adjusted the idle screws in and vacuum when up so I'm on the right track. I probably turned them in almost a full turn to get the best vacuum. I read the specs on the stock carb and the power valve is a 5. My Vacuum is 17-19 so I'm assuming I need a much larger power valve then a five. Anyone put a higher number in?

and if I do put in a higher number... I would dump more fuel at acceleration right?
