Get the carb off the engine and carefully drill or grind.

There was a drill tool specially made for removing the screw caps. I think it was like a very small hole saw, so it removed the cap and casting but left the center threaded area for the mixture screws undamaged. Search some of the Quadrajet parts sites and it may still be available.

You can cut 2 slits with a hack saw blade on either side of the screw at the bottom and the cap will snap off.
