What intakes you run with flat hood?

If it's the Performer RPM, going to be real close. Go to the Edelbrock website and get the intake flange height and mock it up on the engine with a proper width wooden spacer between the existing intake and carb flange.

Next, slam the hood and inspect hood for damage! LOL8)
I f no damage, you're good! If there is damage, cut out damage and install scoop, you're good!
