I've tracked the LS2 402 shortblock fpor months with hopes of doing that swap along with AFR heads. Now this L92 head seems like a much better option, along with the larger bore short block. I hope you guys figure out the intake problem so we can all start doing this swap more easily. I think this will be the most cost effective swap in the coming year if an intake can be had to work on our cars.

Will the LS7 intake bolt up to them?

the answer is no.
the ports are different.
the bolt holes are different.
there is not enough material to make up for the differences.
currently the only production intakes that fit:
the 2007 L92 Truck intake
the 07 holden intake (not stocked or currently sold in the US)

Cause they flow like a **** and are low in cost compared to the aftermarket heads that cost an arm and a leg..
Heres some pics of the L92 intake and engine

really, we need a whole FAQ on it... including that.
EVERY SINGLE THREAD is full of the same questions.. some we have answers to, others we dont.
example:
- Does the LS7 intake fit?? NO the LS7 intake does not fit.
- do i need a new rocker arm locator strip?? we dont know yet, but very likely since the intake rocker has been moved.

gun5I1ng3r,
Remember the "cathedral" portion of the port was simply for the fuel injector to be
able to shoot toward the back of the intake valve and be as close as possible to it,
it is not there for air to travel.
That L92 head is awesome, look how much the port is raised over the LS6...
