6.2L heads
Was talking to a friend over the weekend that races. He says they are building a 6.0L (same as in our H2s) with the new 6.2L heads that are on the new '07 Escalade and whatnot engines. Says they are going to be able get a lot more grunt out of the rebuilt engine with the new bigger heads. Requires a new, possibly custom intake, but someone like Edelbrock will probably be coming up with one soon anyway.
