I believe that is the supply port for the heat tube/chamber to warm the carburetor to keep it from freezing in cold climates.
Mr.Gasket intake gasket kits supply a plugging device to give "you" the option of blocking that heat.
In MY experience a street car does not need the heat passage blocked or more correctly I don't see the advantage of doing that on the street.
Thank you Pantera Doug. Always providing good information.
