Since you have a BG carb you might be able to tune your cruise A/F where you like it with your regular jets. Then tune WOT with your Power Valve jets. A good carb will have replaceable power valve jets which can be changed. You have to remove the Power valve to get to them. Not sure where to buy them cheaply. Or they can be drilled out a little at a time.
