The only issue with putting the L92's on an LQ4 short-block is the compression drop. You're going back down to about 9.5:1 static compression or so (before milling and thin gaskets of course). What camshaft are you running?

With that compression, and depending on which bolt-ons you have exactly, I'd consider our Texas Speed 225/230 LS3 cam or similar!

When you order, we just indicate it is a 3 bolt cam core and everything, including the stock location cam position sensor, will work perfectly!

dont overlook what Matt said above about compression... personally i think youd be putting a lot of money in while getting very little out. in addition to the heads, you will need a new intake manifold so get ready to do the 'full intake' again. The heads will flow a ton but with the killed compression i think you may come out even on power and possibly down on torque with those huge gaping intake ports killing velocity.

LQ4 pistons have a dish, right?
watch getting a big cam anyway... my cam did not have enough clearance with my LS2 bottom end unless my L92s were unmilled and using a GM .052 gasket
good luck
