I've seen some of those intakes that were a bit too short for a standard carb which allows an air leak at the slots for the mounting tabs of the carb - once,I saw one designed for a special carb that was about 2mm less in its outside diameter for the standard carb to get a tight fit.

Sounds like an air leak to me would be my first guess.

What would you do?

I'd first put a standard intake on it to be sure that is the problem - then, I'd see if it were fixable.

I have tried 4 different carbys and same results with 4 different styles of air filters and same results. But the same intake billet itsgotta have an air leak. There are no gaskets? WHAT TO DO? its been a paper weight in my shop in a ziplock.

I tried some s**tTY Blue gasket maker for high temp (above 500%F) but the stuff never dried like it said it would!

make the gaskets out of cardboard... cruddy old cereal box makes far better gaskets than s**tty blue gasket maker

as mentioned, make sure the carb goes completely onto the manifold stub, if in doubt, scribe a line, measure the depth of carb throat, measure from end of manifold to the line scribed, make sure theyre the same...

I found some O-Rings when I returned that cruddy blue gasket crap. I had am air tight seal I tested it (SPRAY TEST) NO LEAKS. And it still only runs on 1/2 choked!!! So I'm returning it via U.S. Mail they said they will investigate the piece and situation and either credit or new billet.
