Default Mod Suggestions for l9H

I have a 2012 Sierra Denali 6.2 L9H and looking for suggestions for my next mod:
216/228+8 112lsa vvt cam
1 7/8 speed engineering headers
3" true duals
airraid mit intake tube
black bear tune
stock stall
stock gears
stock tire size
I use the truck to tow and I want to keep as much low end torque as possible. I'm thinking ether 4.10's or a Fast lsxrt manifold.

I wish that was in the budget right now. What's everyone's opinion on the zl1 converter? I don't want to get too crazy with the stall because of where I tow.

G8 guys love them, no experience in the truck with one, but when I had a G8, I rode in a LSA car with a ZL1 converter and it straight ripped outta the hole. A good cheap upgrade except for the damn core charge.
