Question for Holley jetting pros.

Or at least someone who knows Holley's better than I do when it comes to jet changes.

Yesterday I swapped my Edelbrock 1406 out for a Holley Avenger 770 with vacuum secondaries and my air fuel ratio is a ways off.
Any guesses as to how many jet sizes I need to drop if my A/F ratio is in the 10's or high 9's?
I have the idle A/F set where I want it, but anything off idle and all through the throttle goes into the low numbers.
Right now the carb has 72 primary jets and 75 secondaries.
How many jet sizes do you think I need to drop to get it around 13-14?

Thanks all.
