FiTech EFI system

Would it be better to run these throttle bodies on a regular intake instead of an Air Gap? The only reason I put an Air Gap on was for the carburetor to try to stay cooler. That's not really such an issue with TBI with pressurized fuel at 58 psi going to it. I'm just wondering if the longer runners and intake volume is good or bad.

While you won't really have hot start fuel boiling issues, you will also not have to worry about heating it up with a TBI either.

Since it's a TBI, the runners and intake volume would be like a carb as it's still a wet-runner intake. It's likely a bit better atomized than with a carb, especially cold, but seriously, the air gap is a good manifold. Hughes even makes one for the magnum engines with port EFI.
