Edelbrock RPM Airgap Bolt Hole

If you watch the edelbrock tour thats on youtube you will see they hand finish the intakes with a die grinder. I have a couple air gaps and there is one bolt hole that a stock length bolt wont fit in because the runner is too close. Maybe this was done to address that.
My new RB six pack intakes has all kinds of dings inside the runners and in the plenum. I assume its from an air hammer used to knock out casting sand. Not a great thing to see inside your new intake.
