    I would not recomend that.... holes in the back would allow the air to exit at the rear, which would mean the air would want to move over the tops of the carbs which would lower the air pressure over the tops of them which is not what you want.
    The whole idea of the scoop is to let the air pressure build up over the carb venturies.
    Besides, I personally think it would look ugly.... :shock:
