Things could run a little different, he lives in LA. and you live in MN.

Go with the non air gap..........

Before the Air Gap intakes were around . We would just block off the heat ports . And run a Lifter valley tray . By do so the intake would stay much cooler . But when driving the car on below 50deg days . It would be like a car with no choke . And after say 50 min of driving with the under hood temp higher . Then the car was more drivable . The Air Gap will do the same thing in below 50deg days . If you take out your rod on the more warmer days then it will work great . Because on the hot days with are old set up . Or with the new Air Gap . Your manifold will be at a much cooler temp . The chance of Vapor Locking is next to none . Or you can run the non-Air Gap intake with the heat ports open . And just the valley tray that keeps the hot oil off the bottom of the intake . I do it this way on a car that is more street then strip .
