hood vents

Any of u guys ever put hood vents in a fiberglass hood ? I have a tremendous amount of underhood heat. Even w/ the headers , and comlete exhaust wrapped. Just running on the edge of overheating-almost. thinkin a nice looking pair on each side of the 6 pack scoop would help tremendously, but don`t want rivet on cheazy looking ones.
ive done it, are you wanting to fully glass them in to make it look like it came from the manufacturer that way or screw/bolt in?
