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...
Every time I see one of those 1,000 cfm units pop up for sale, I’m out of piggy bank money. I have one now. When I get the piggy bank back up to spec, I’ll look for one of those or another electric choke MP throttle armed TQ’s for a matched set. Like the Avatar.

1:1 linkage, both being drawn upon at all times.

Research indicated to me that progressive works well on low rise dual plane, dual quad applications, where tunnel rams like 1:1. I have no experience with it myself yet.
I believe you are correct.
