dual quad low profile?

i am runing a edelbrock thunderseries 800cfm AVS carb on my 340 and its a square bore design its just like any other carter afb or edelbrock carburator except for that the airdoor on the secondarys can be adjusted very easily and in my opinion these carbs are much easier to work on than the holley design, if i where to use a dualquad manifold i would go for edelbrock carbs just my 2cents ;)
BTW is there anyone that has a picture of any of these manifolds?
