GMPP will sell the heads complete fully assembled for about $700.00 a pair.
The good news is that they plan to offer an intake kit also. The intake will come with injectors, fuel rails and a 90 MM throttle body. The target price for the kit is $475.00.
The L92 heads and intake kit will be a very cost effective performace upgrade for the LS engines. Look for the heads to be availble 3rd quarter.
I will advise more on the intake kit when I get a release date.

An upgrade to LS engines? Maybe I missed something, but don't you need a 4.00" bore to use these heads? Seems the LS1/LS6 guys with the smaller bores are out of luck. Please correct me if I am wrong.

Guess I will have to ante up for an LS2/L92 block when this stuff becomes available.

I thought they used 2.16 intake valves?

I'm putting together a 446ci Darton Sleeved LS2 super stroker with the L92 heads/sheetmetal intake and would love to see 360+cfm out of these heads. This is all being put together thanks to MizFit Motorsports! I think you've talked to Taylor about this, but I'm just wondering if you have thought about it anymore....my heads are at his shop now
Thanks!
