Edelbrock Air Gap on Magnum 318 Problems

Thanks fellas, it looks like the one item nobody argues is the intake. I was told by a pro the intake plenum was too big for a 318 and I would need at least 380 ci to make it work correctly. Today, I'm gonna order the Holley pump tuning kit and see if I can get it worked out.
This is the kit I'm gonna get...

Is there a vendor on here for Holley parts? Streetside has fast shipping and a great pricing.
