RPM air Gap problems?

My Edelbrock six pack intake was way off when the machine shop went to port it. Since they removed so much material from the ports it didn`t really matter, but if that wasn`t the case it would`ve made a terrible match to the heads. Edelbrock has some quality control issues and they need to rework the casting of that manifold because it was at least an eighth of an inch off at the ports.
