Holley Pro Dominator install. Carb setup

Back in 2018 I knew a fella that had a pair of competition thermoquad 850s on a max wedge....I bought the pair of carbs...now he has a pair of thermoquad comp 1000's on a edelbrock STR-14 on a 440...looks insane ...those AVS-2 carbs are great pieces and I would like a 800cfm one for my big block...
