Any benefit to cutting holes in hood underneath scoop?

I put the dual scoops on my Dart GT and drove it that way for years. A few years ago I made them functional. I didn't notice a difference one way or another.

If you plan to make them functional, I would recommend the seals from DMT. However, I would also suggest some "practice" holes in some scrap material using different sized hole saws.
