Get used to searching with L92 and LS3 filters. Aside from yours having flex fuel, it's an L92 and aside from it being the truck variant, it's "basically" an LS3.
Call them, their customer service is top notch and the guys know what they're talking about. I have placed 5 orders from them and the only time I did one online was because I didn't have my debit card on me while I was on the phone.
25-LS3Camkit660 is the cam kit you want. It will give you drop downs to pick which cam you want, spring kit you want, oil pump etc. I would go ahead and replace the oil pump since the front cover will be off anyways. When I had mine apart doing everything I put the Melling High Volume 10296 pump in along with the pickup tube Orings and I'm running about 30psi hot idle, 40psi while driving, 60psi cold start on 192k mile L92.
CHE trunnion upgrade = Yes
VVT delete is up to you, I did it because of the cam I selected, not everyone has to though.
Think about getting a converter unless you want to keep the cam pretty mild. TSP sells a Circle D for our 6.2/6L80 combos and it works great.
The following is the most important part
No matter your options above. DO NOT get anything other than the following for lifters, trays, gaskets.
Lifters 12499225
Head Gasket 12610046
Trays 12595365
Those are the gmpp lifters and gaskets, not an oem ls7 setup or knockoff parts. But the good stuff. Trays are oem but are the only ones that should go in your engine.
+1 for the parts recommendation, and my personal recommendation would be to get a VVT-friendly cam.
