Good starting point..................076 (Holley) or .098 with 035 to 037 Rod tip

Big Carbs................................. .143 and .780 Air door to start

Open Air Door 020 at a time on dyno and see what A/F and HP changes.

I prefer 6453 carb as it came on 360 but not critical.

I worry more on AVS carbs switching as they have tabs on boosters for
different engines and manifold combos for air
flow correction ( I think that is why they are there).
