Gen IV truck engines?? Aren't all the Gen IV truck ans SUV engines using the intake port design of the L92's and heads based off the L92 design.
So wouldn't that mean any of the intakes off the 4.8/5.3/6.0/6.2 are all common on the new body style 07's Suv and truck V-8's.
So any intake off the engine would fit the L92 heads right?

The valve size/layout of the L92/L76 heads only allow it's use on the 6.0 and 6.2 (and larger bore'd) engines. Only the 6.0L and 6.2L engines are using the L92/L76 cylinder heads, therefore the L92 and/or L76 intakes only fit those heads.

High-flow cylinder heads
The Vortec 6.0L and 6.2L engines offer a significant power level increase compared with previous premium engines, with much of the newfound power coming from high-flow aluminum cylinder heads. The heads are based on the racing-derived cylinder heads of the Corvette Z06’s LS7 7.0L engine, including a unique inlet port shape and offset rocker arm design. Airflow of the heads is supported by large 55-mm-diameter intake valves and 40.4-mm-diamter exhaust valves.
“The heads use the high-performance technology of the Corvette’s LS7 to build efficient power in truck engines,” said Meagher.
Vortec 4.8L and 5.3L engines also have high-flow, Corvette-derived heads. They are based on the previous-generation Corvette Z06’s LS6 engine’s cylinder heads and have flow characteristics commensurate with the engines’ airflow-to-displacement needs. All the Gen IV Vortec engine variants use the same efficient ignition coil packs of the LS2 to light off the air/fuel mixtures that are drawn through the heads.

Looks like the 4.8/5.3 Gen IV engine use a Gen III Z06 based head so I guess their Intakes won't work with the L92 heads! Unless someone has actually seen them.
