I don't know about the head. I know the intake plenum is cast differently, at least for some models; The material isn't even there for you to drill it out.

It seems the heads themselves are indeed drilled for EGR:

There are a couple owners in there who mention their engines coming with block off plates on the head.

Fuel maps may not be the only difference but also the timing maps they're running.
