To some extent IMO this whole thing about where to put the regulator is over done. Its all about hydraulics. The pressure is going to be the same throughout the line whether it is place before OR after the carbs. The reason for having the regulator in the first place is to limit the line pressure because the design of the Needle/seat and the mechanical leverage imposed by the Weber design float is not capable of creating a leak free seal when the pressure is much above 3 lbs. There is no "Cushion" at the point of seal as in a Holley because the Needle/Seal assembly is made completely of Brass without any Viton tip (which would be a great improvement), or if the Groose brand (sp?) ball type valve were still available in any size but 3.0.
