What is a correct tunnel ram linkage?

I spoke with my friend who does my machine work and he told me they have turned the carbs in the direction Grumpy did. He said with the primary bowl facing the passenger side of the car, the fuel level will move down under acceleration. With the carbs facing the way Grumpy did them, this will not happen. He said the fittings are to vent the bowls and was a trick that worked great.
For what it's worth, he told me the linkage that Dave recommends is the one most everyone bought and used back then.
