Mounting Thermoquad to air gap style intake. What adapter?

Edelbrock has two different spreadbore adapters, QJet-2692, and TQ-2691. Go back to Bill Crowells post on Feb 3 2021, (Squarebore V spreadbore). I added several pictures on the difference. I would use an adapter on a 340-360 before I would use the Edelbrock 318-360 Performer with the 318 size ports, plus that 318-360 Performer in down right ugly! Go back to Bill's post-very informative, if I say so myself.
