No it will not. With a lot of modification it could though.

Has anyone seen anything about the flow rates on these heads as-cast and/or ported at various lifts? If so, where can I find this information?

Thanks,

Nope, the runners are too wide and you would end up outside the o-ring. GM or sheetmetal.

Yuck, that is a scary proposition with even a stock shortblock, much less a nice forged setup. Too many epoxies fail.

So will the GM truck intake definately bolt to these? because so would my Magnacharger?

Article says they will work on LS2 so I guess we can assume any 6.0L derivitive block.

That is fabulous if we can be assured of an intake that fits under a Ybody hood. Seriously fabulous.

Actually, the L92 and LS7 heads should both work on any LS series block with a minimum bore of 4.00" However, the interface between the intake manifold and the intake runners is different. The LS2/LQ4/LQ9/MagnaCharger RADIX/All Current Aftermarket Manifolds are set up for a cathedral roofed style interface. The L92 and LS7 inlet ports are rectangular and are different from each other (mainly in height as far as I can tell). Unless you can get and use either an L92 or an LS7 factory intake manifold, the L92/LS7 heads won't work. I'd about guarantee though that MagnaCharger and everyone in the aftermarket intake manifold business for Gen III/IV is developing manifolds now. I'm sure too, that the factory LS7 and L92 intakes probably flow well in their current state. However, if you want to use an LS7 manifold on an L92 head, there's going to be a pretty big mismatch. If the L92 intake runner were ported to be properly matched to an LS7, that would probably work fine.
