I have an Eddie Edmunds 2 deuce intake. There is one just like it on Ebay right now. Search '216 Chevy'. The listing mentions that it will fit a 235 - but they must be talking about the old 'Hi-Torque' - as the runner holes are not large enough for the 235/261 head.
These intakes are designed for three bolt (ford flathead) carbs built on the Stromberg EE-1 base, and the smaller throat EE-7/8 base will bolt up as well.
To get to three deuces you will probably have to go the adapter route on an Offenhauser or a McGurk. Langdon's was mentioned for an adapter to a 4 bolt carb (Weber). There is a place called Vintage Speed that sells a three bolt adapter -- making ford venturi's an option (Stromberg 97/81/48s or Holley 94s) depending on the cfm you're after.
You can checkout their online catalog under 'fuel lines, blocks and carb adapters':
