Valve cover fitment issue with RPM Air gap intake

The intake should be fitted to the head and milled off as needed when the engine is built. How would you put revers flange valve covers on if that is not done pictured below.. The factory tin covers and some after markets have the notch cut in for the runners on the intake. But leveling them off is a plus for sealing properly.
