Is there any vacuum take off on the carbs ( I would expect them to have them ) and hopefully each carb will have a combined vac from each venturi.
A check valve is a one way have to prevent one carb from sucking from the other. Ford ones are usualy white and black things with a port at either side. So long as you have a feed from each carb and each carb has a one way valve you should be ok.
