Yes, with the latest version of the Dutra casting, we can set-up the manifold to be used on the rear 3 cylinders.
There are a number of dis-advantages to this, you named most of the issues such as no carb heat, no auto choke "stove pocket" and starter clearance. The new "mini-starter" allows pretty good clearance, the larger "old" starter is in a little closer and makes pipe routing more difficult.
I have this "dual duals" set-up on my drag car now and I will do some testing these weekend. I will letyou know how it flows.
