The L92 heads are pretty cheap and are being used in the GM trucks such as the VortechMax 6.0L (L76) and in the Denali line and the Escalades, so GM is already making alot of these new rectangular port heads (L92) based off the LS7 heads. Also GM has a L76/L92 car intake that is supposed to be released from GM Performance Parts any time now, already available in Australia, for the L92 heads which means GM plans to put the heads into cars in the future.

So why would GM introduce a more expensive, more parts to break, and unproven 3V head in a mid-cycle Corvette?

I think Direct Injection won't be available either until the C7.

The ZO6 will still be around with a LS7 with (maybe) a slight bump in hp for '08.
