That adapter is a good beginning, if the hole in the original manifold is bored bigger to accept the increased volume the 2-BBL is capable of delivering. I'm thinking of making the hole inside the 1-BBL flange about 1/2" or so larger, and installing a pressed-in sleeve to account for the fact I'll be opening it up into the heat riser passage.
