Edelbrock Performer or AVS carbs for 318 dual quad?

650s !?!?! EEK!!!! I've got 2 500 Eddie AFBs on the STR-12 on my 340. I can't imagine why you would use 650s. If you are going to open the carbs at the same time, no reason not to use the same carb front and back. By the way, I used Performers (AFBs) because they didn't make AVSIIs in 2005.
