The air-gap intakes are great intakes. The only problem you might run into is with the vacuum port if you are planning to use a Holley carb.

The port sits so high that it comes very close to the secondary accelerator pump on a Holley and you will probably end-up having to run at least a 1/2" carb spacer to give you enough room to get even a low-profile vacuum fitting in there if you need it for power brakes or trans modulator or some other vacuum accessory.
