According to the article in GMHTP about the new Pontiac G8, it will come w/ the L76 intake and a small bore version of the L92's. I'm real anxious to see/hear more about them myself.
Here is an excerpt:
G8 GT-L76 6.0L V-8
If you've read this magazine for any measurable length of time, you've undoubtedly heard us bantering about the L76 intake paired with L92 cylinder heads. Oddly enough, up until now we didn't even have a vehicle in the United States that used this particular manifold. The good news is that not only do we finally get this mystical intake, we also get cylinder heads that fit the smaller bore-but with the same benefits of the L92-style heads, including the rectangular LS7-style intake ports.

From that little bit above I doubt GM will make a new head. The L92's already fit on a 4inch bore so theres no reason and would be dumb of GM to spend money for motors no longer in production, that being the LS1.

The L92 small bore heads from ETP are supposed to be coming out in July.

from the link i posted: In basic terms, the L76 is a natural extension of the LS2. They share a similar bore (101.6mm LS2, 101.3mm L76), and the same 92mm stroke
And 6.0 heads are small bore. You can put 6.0 heads on an LS1, right? That makes the heads in this article "small bore". The important thing is the valve size and spacing for them to fit on a smaller bore.
