Power Valve Selection: The Definitive Answer

I just installed the 10.5 power valve and dropped the primary jets from 72 to 70. Went out for a long drive and my lean stumble at part throttle is gone. My cruising A/F ratios are now in the high 13's, so heading in the right direction. My idle A/F ratios did not change at all, maybe a touch leaner if anything, so the fact that I have a 10.5 power valve and 8.5 inches of vacuum at idle is not a problem. I will be headed on a 1 1/2 hour trip to Moparfest in the next two weeks, so I will leave it like this for now and see if I want to drop the jetting again.
