Experience with Ajay and Matchless twins taught me that it is very undesireable for the heat to transfer to the carb(s). They would suffer terribly if no insulation was provided from the heat.
The original fitment was a "Paxolin" or "Bakerlite" gasket which went between carb and manifold...So the manifold was still allowed to get hot with no ill effect...And was frequently polished.

I would say that the Ducati set up with large rubber adapters to mount the carb to the tubes would provide ample heat insulation..........Polish away..
