AIR GAP INTAKE WORTH THE MONEY?

I ran an AirGap on a 340 for a while and the engine was tuned on a chissis dyno producing 325 horsepower to the wheels with a 284/484 MP cam and port-matched heads. Otherwise a stock build. 10.2:1 CR. Although the AirGap cost a lot, it worked well and I am trying to save front end weight as I want the best handling I can get. The car is under restoration now and I am going with Edelbrock heads to save additional weight. This combo will have a Performer RPM with a TQ for better street drivability. But still saving weight is my goal.
I like the Mopar Action article where they put aluminum parts on a 383 and got the weight down to that of an LA engine while adding HP. Never a bad result.
