Offy 5041 dual 1 Barrel carbs?

The manifold does have a plenum between the two carbs. It is recommended that some sort of water heat be plumbed up to the bottom of the intake. Also, I found out that the carb mounting pads are large enough that they can be re-bored to accept a 2-bbl carburetor. I'll let everyone know what else I find out when my 5041 gets here.
