GMPP Vortec TBI intake manifold?

I was sifting through the GMPP catalog (all 383 pages of it- 39MB download size) when I can across something I hadn't run into before- a high performance TBI intake designed to fit Vortec-style heads. It's part number 12496821. It looks just like the Edelbrock TBI intake manifold except that it's designed for Vortec-style heads (it even has EGR provisions, although plumbed in externally like all Vortec intakes, I'm sure).

Anyone seen this or have any experience with it? It looks like a no-brainer for somebody who wants to keep their TBI but use more modern design Vortec heads in place of their old swirlies. Of course, you could use a Vortec carb intake with an adapter plate for less money, but this looked interesting nonetheless.

It is about the same as the Marine/Export L31 manifold.
