Getting Rid of Rear Hood Vents?

[Marauder]

Getting ready to paint my '69 GTO and I am pondering getting rid of the vents near the rear of the hood up by the windshield for a cleaner look. I saw that Foose did this on a '69 LeMans on Overhaulin'.

My car is a factory A/C car and it lives in Florida so I don't want to compromise the functionality however if by switching the A/C to "MAX" closes a damper to the outside air and simply recirculates the cabin air I should be fine. Did they have this feature back in '69?

I understand that the Firebirds after 1976 got rid of these vents as well.

Anything else to be concerned about by doing this?
