Inlet Exhaust Manifold Question...!???

[Chris KC]

You could easily convert it into a single carb manifold by cutting back the two inlets and welding on a log type piece with single central carb flange.

Or easier still cut off the inlets, file the face flat and mount an inlet onto the existing studs. I think John Barlow does one for SU which would suit. You may have to use an imaginative combination of tube nuts or perhaps allen screws instead of studs in order to have sufficient access to tighten them, but it can be done.
