I have been trying to get good information on the L92 Heads. We have been playing with them a bit and will share that information when we have good data.
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.

Yeah you need atleast the 4" bore, they are setup for a 4.060 chamber and use 2.12 intake valves.

Thanks xfactor...for second I got excited about a L92 top end on my car
Guess I will have to ante up for an LS2/L92 block when this stuff becomes available.
Just know that because I am awaiting a set as we speak. Eager to get started on the custom intake.

How is GM getting 10.5:1 compression with a 68cc combustion chamber? Are they running really thin head gaskets? I am assuming the pistons are flat tops, anybody seen one?

Well its a 4.060 bore, with 68cc and about a .050 gasket you are right around 10.5-10.6:1 with a flat top.

Have you gotten anything in the works as far as cnc or porting for these budget heads? It seems like these will be a VERY popular option, especially with the pricing. 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
I believe it's a 4.065 bore could be wrong but I remember somebody saying that.

My fault, just shot from the hip. Either way, its more valve than you need for that bore size.

I'm supposed to have a couple of sample heads on the way. I'll start working on a program as quickly as I can.
