Mounting Thermoquad to air gap style intake. What adapter?

After kicking this around over the winter I think I am going to bag this idea and use my TQ on a LA 360 that I have for a future project. That engine has a Eddy Performer manifold. Now what to use on my current air gap style intake? Right now I am running an Eddy 1406 600cfm carb. I think it is under carbureated. I also have a factory refurb 670 street avenger but have not heard good things about them. Leaning towards an AVS2 650 or a 750 DP. I know nothing about Holleys but no expert on Edelbrocks either. I need choke and would rather have mechanical secondaries.
Recap..engine is 9.3:1 360 Magnum with small valve EQ's and reground 218/224, 270/277, 525/535, 108. Hughes springs. Street driven with AC
so idle rpm is an issue. Please don't let this get into a Holley vs Eddy battle.
