Carbs you have:

That manifold will only take AFB-type carbs, so no Holley or Quick Fuel carbs. You may note Edelbrock recommends two separate carbs - one with manual choke and one with electric choke. You currently have two manual choke carbs. There's nothing inherently wrong with that, as long as they're properly set up.
If there's nothing wrong with the carbs other than disconnected secondaries, have you thought about just getting the secondaries properly re-connected and trying that before you start all over? Dual quads are cool, and it would be nice to keep them.
