While the responsive-down-low does sound like it, if the cam were advanced, though, I'd expect strong idle vacuum. If it were late, I'd expect it reduced.
I really am not in the mood to pull it apart and degree the cam just to chase a number when there are no other symptoms (but I verified with a new gauge today that it's only got 11").
I also disconnected the vacuum booster and accessories today to rule them out as a leak source, no change.
My cam specs follow - it's more than stock, but not big or wild I wouldn't say:
Intake: 214
Exhaust: 218
Lift: .496
Int Cntr: 110
Ex Cntr: 120
Overlap: 66

Your cam numbers don't mathematically add up
what is the intake duration and the exhaust duration and the lobe separation angle (LSA)
