Any benefit to cutting holes in hood underneath scoop?

On my wife's 75 Duster 360, it's got a Dart Sport scoop. I keep thinking about buying some grommets and cutting holes in the hood, but then before I do something that's not easily un-done try and think what the upside would be.

Do people with vented scoops ever see any realized upsides such as lower under hood temps?

I recently saw pictures of a duster with a Dart Sport scoop on it that someone had posted on facebook, he went as far as cutting the hood opening big enough to graft in an air cleaner lid, then used a thick seal so that when the hood was closed, it functioned as a real fresh air scoop. This car gets driven in the rain, so I'm not sure if it'd be a good thing at that point.

Shanker long time no see. Like said the rubber will deflect minor, light rain.
I took pictures but waited to long to post them. Looks like been addressed allready. I pulled one off and measured it.
They are 3/4 inch tall. They do clean up the holes and give a finished look.
As you can see most of the,seal is on the outside of the hood. Sorry for the bad pictures.
