My last build I back to backed Cater 750 comp to Eddy 750. Ran exactly the same. Mine are an older pair , maybe the new ones are different. I've run smaller and "unliked" carbs on many street/strip 11-12 second builds with success. I not saying to buy or not buy. I can tell you I've never had a carb I couldn't make work. Like I've stated before. I run AFBs,Holleys,T-quads. Depends on the application.
