If you're using the correct 0.100" thick O-ring on the carb flange,you'll have about 0.050" gap between the flanges.You should be able to rock the carbs when they're tight enough.It reduces float bowl vibration as well as heat transfer,and it's a good system.
Don't overtighten and bend the flanges.If you bend the flanges,the throttle slides can stick.
