is there a difference between installing a weber dgav with the linkage on the firewall side? or the radiator side?

My 86 2.0 liter came with the crappy empi clone weber with the linkage installed in the firewall side. So when i put on my real weber i put it on the same way and reused the linkage setup.

Looking through the secondary barrel, i can see a part of the manifold blocking the path. that seems crappy and somehow it seems like it would cause vaporized fuel to drip there when the secondary opens. since the primary is a lot smaller, would it clear that blockage if the carb was reversed?
