The current GM High-Tech Performance magazine has a couple of really good articles on these heads. (Feb 2007 issue) In this same issue I quote "GMPP shoehorns a brand-new LS7 into one of its Camaro test cars, and we slaughter an innocent T56 in the pursuit of 11-second timeslips."
Its a good issue... check it out. It will explain a lot of questions.

If so, will they require different rockers and longer pushrods like the TFS and ETP heads?

theres alot of great info in there about the L76/L92 setup. also in response to powershifts question, the strut tower brace should still fit as its not really a truck intake..they designed the L76 to work with the L92 heads as the truck intake wouldnt clear the hoods of most production cars. the main difference between the L76 and ls2 intake is the difference in runner length and they actually will meet up with the intake ports on the L92 heads. i REALLLLY wish i had the money laying around as this would def be my next mod
Add a lunati cam with some nasty specs (595/595 238/242 112lsa) to the L92/L76 on an LS2 shortblock and you've got the makings of a 500 whp daily driver. 
and yes the Nick Williams 90mm 4 bolt design will fit.

Nice,
where are you from? The brake system seems to be on the "other" side in your pic?
I see a nice Hydroboost system too...
Guy's,
I just got an LQ4 (if its what its called) out of an '05 Hummer. What would you suggest i do with this? I'm not very LSX informed yet on the possible interchanges with those motors. I have a freakin tall intake that kinda look like the one here but...not really either.
I want a big power (i also recently got a set of twins for a song -t4's- and am toying ideas around) and a Big lope would be nice (Hey its a '69 after all!!!). To tell you, i'm not even sure yet what i have in this LQ4...I got it because it was a good deal too (last week).... and i'm completely overhauling the underside and front clip of my Camaro right now, so i'm thinking i might install the 6.0L now instead of next winter.
Thanks for any help!

The current 90/90 setup won't work because these Heads have the rectangular ports, just like a LS7 Head. The current 90/90 is for every other Head with Cathedral ports. The LS2's have the #243 Heads, same as the LS6 Heads, just without the Sodium filled Valves. The L76 Intake uses the LS2 Fuel Rails, and the LS1/LS6 Style Fuel Injectors. I put LS2 Injectors on mine cause I got them cheap, and had to shim the Rails 1/2" on the mounting spots. You have to relocate the MAP Sensor Connector in your Harness to on the right side front, basically next to #2 Fuel Injector, about 4" in front of it. The stock Truck Coolant Cross-over lines will bolt on to and work with these Heads. You have the 2 in the back that plug it, and then you have the one in the front that crosses over and goes to the Radiator.
I have researched this for a little bit and have all these products at my house, so ask if you have a question. I can get all kinds of pics also if you need them.
I just got the L92 Heads, L76 Intake, and a Holley 90mm Throttle Body, here are some good pics, enjoy..

The intake that most reffer to as the L76 is actually a car intake that is used on the Australian market L76 engine. For the most part it is a truck engine with a car intake.
So there are actually TWO L76 intakes, one for trucks and another for cars.
