It depends on your definition of the word, "functional". If you mean as a ram air, you are better off going to an aftermarket hood. If you mean as a vent for engine heat, go for it. Simply drill one or two 1 inch holes under the hood scoop and remove the plastic insert. This will serve no different then the vents in the GT500 hood.
You will also need to remove the hood pad inside and cut a small hole for the air to enter/exit. This is very easy as I had to do this when I installed my VIS hood. Use Gorilla tape around the areas in the hood pad you cut. I had to experiment with various tapes in order to find one that hold up to the engine heat.
I just replaced my entire hood with the VIS Stalker hood and love it. If you make any mistakes on the drilling, I am selling my factory hood cheep.
