The part numbers are in this thread.

That's no deal - that's just the price. The only caveat is that occasionally trademotion, the backend that Duval uses, is a bit out of sync with MB's current pricing. Most of the time it is right on the money. As gsxr mentions though in the linked thread $1600 is about the going rate. If you buy from Duval you are going to pay shipping while Fastlane or Rusty might pay that out of their markup.

From Duval's description in the attached screen shot the head isn't really "nekid" although Dave has mentioned that you may (or may not) need some machining on the #22 heads.
