Any benefit to cutting holes in hood underneath scoop?

My avatar car (72 Demon 408) has a 6-pack glass hood in it. I was concerned about vapor lock at the track since I don't have a cool can on it. To date, I've not had any vapor lock/heat related issues with it. Surprisingly, I can even leave the hood down and not see any issues. Perhaps the chimney effect of the scoop helps? I dunno...but it sure is easier to deal with at the track than my 69 Charger was!!
