Since we're just talking here, I'll add that a spec head that is CNC ported from the factory is easier to police against stealth modification. If there's any doubt about whether a head has been tampered with, the manufacturer can scan it, or run it throught the machine again.

In order to pass, it not only has hold the correct volume, but the shape must be identical as well. With CNC, there can be no arguing about how you found a "lucky casting".

The only reason that I don't like the idea of a "spec" head is it's not practical to pull a head and check the shape at the track. I guess it could be done with templates but I could see "stuff" slipping through. If the intake tract is restrictive enough (very small spec carb or throttle body) and the valve spring pressure is restricted then the RPM potential of the engine would be restricted to a point that the head and intake become less of an issue. Compression would then become an issue but I guess that a spec cylinder pressure number could be easily enforced.
