Hot Rods dual carbs

I bought a two carb manifold for my banger. I have two Holley 94s for it. I had to lean the one down when I ran it on my Model A but not sure about the other. What modifications will I have to make on them. It's .060 over, "B" cam, 7.1 head and in a very light speedster ch***is

Two 94s are a lot for even a warm banger.
FWIW, I've been fiddling carbs for sixty years and didn't know how much I didn't know until I got a direct-reading O2 meter and wide-band sensor. I'm older than most Hambers, but willing to admit times have changed. With today's gas, the art of tuning carbs by reading spark plugs, that was then, this is now and it doesn't work the way it did back when.
Bottom line, find an O2 meter and start from there.

I have a pair of 81's that I'm thinking about running on a banger and they might even be too much. A pair of 94's is around 360 cfm, we used the ratio of 2 cfm per cubic inch years ago but that was on a modern overhead which is a lot more efficient than a Model A motor. I ran a single 94 on a B motor with a Winfield head, Mallory distributor and a header and it ran great.
