You're right about the intake being hard to find. I did find one company offering a billet intake for the IDF/DRLA carbs or TB's, but it was $1600 bucks!!
I'll make my own if I have to!
The guy in the link below made his own IR intake from an Edelbrock Pro Flo LS1 intake. He's using throttle bodies instead of carbs, but the manifold would pretty much be the same. I'd have to check and see if the intake runners on the Pro Flo manifold match up pretty well with the Weber IDA or IDF pattern, and choose carbs based on that. Aluminum carb flanges are easy to find and could be welded onto cut down runners of the Pro Flo manifold; assuming the runner spacing is ideal.
