Fiberglass 6 pack hood get the heat out?

Hi everybody:

I'll probably be getting one of the fiberglass six-pack hoods from Stinger like on this Dart below. I think they look pretty cool but the main reason is to get some air in and out when it's baking hot out. The car does great going down the HYW 185' but if you get stuck in traffic the temp shoots up. Will that light scooped hood help cool things down any? I just got a shroud made a few days ago also.
