Re: Letting the heat out. 67 Hood louvers with vents...
If I wanted improved cooling...
...I'd put an air-dam under the radiator support. Possibly with some extensions along the front part of the frame back to the front wheels.
This would create both a high-pressure area in front of the radiator, to force more air through the radiator, while creating more of a low-pressure area under the car to pull the heated air out.
It wouldn't require cutting the hood. No water in the engine compartment when it rains, or when you go through a car wash. No rust at the edges of the hood cuts where you forgot to prime and paint the edges of the holes. No fumes in the cabin.
Pretty-much zero downside.
