do you mean "Would" (grammer) have to do any work to put a twin throttle body manifold on a 304.
If you dont want the motor to be a slow POS then yes, work is required to get the most out of a Twin throttle body manifold,especially on a standard stroke motor, we are talking Cam shaf something decent, more comp, cubes will help etc etc.
