An aftermarket manifold won't increase the amount of air/fuel your motor can process. The charge that gets processed is dictated by the cylinder displacement and cam profile. If you aren't changing the motor internally at all, then throwing more air/fuel at it is worthless if it cannot process what you are giving it. A 600 is too much. You'll waste gas and it'll run like crap.
If you want a larger carb that will work well with your current configuration, improve off-road performance, and support potential future engine mods, I'd agree with the Holley 470 Truck Avenger for the 304, or the 670 for a larger motor.
