Hole in Head?
Just started assembling my Pro Topline Vortec heads and when I went to chase the rocker stud threads, I discovered that the factory drilling penetrated the intake ports. This has occured on all 8 intakes. The penetration is about half the width of the drill on each. Is this going to cause any serious flow problems. The exhausts are fine. Thanks for any help in advance.

Use a good sealant on the threads. If the flow disruption bothers you, fill 'em with JB or similar goop.
