2006 silverado 1500 and ly6 engine/4l80e trans

Hello all. I just picked up a new project and turns out the swap the seller intially thought was a lq9, it actually a ly6 with the 823 heads and I also got the 4l80e transmission
So the truck is a 2006 silverado 1500 with 5.3L.
Beings the lq9 would have been a direct swap for the most part, now that the swap is actually a ly6, I have been searching endlessly to see what i have to swap.
For starters the truck will be a mild street setup with weekend trips to the drag strip. My initial plans (actually its a good customers of mines project) were to do the lq9 block/l92 heads/ls3 intake with a mild cam to try to reach somewhere near 450-480hp.
I will also be getting hptuners.
So now since I have what appears to be this vvt engine, although it comes with the heads i want, I am stumped.
Some questions I have:
I still have the 5.3L i can steal parts off of. What do I need to delete the vvt?
I do plan to get a cam as well so not sure if that changes what needs to be done.
Comp LSR™, 265LR HR12 which is 265/273 and 604/610
Which valley cover do I use? I noticed the 5.3L gen 3 in the truck now has this two wire connector with black plugs on the valley cover and the ly6 does not.
Is the ls3 intake worth getting over the ly6? And what am I getting myself into putting it into the 2006 gen 3 truck?
Thank you everyone for the help!

U can get a package from mast motorsports that comes with cam/springs/ harness / ecm that will make it 505 hp . This is what I did. Or u can get a vvt delete kit from Texas speed, buy a cam, ecm, etc and tune yourself. The knock sensors are on the side of the block on ly6 .use those and leave valley cover on ly6 .u can also get an ls3 loaded intake that comes with injectors tb etc .u can use truck accesorys with some slight mods. Research everything

thank you for the replies. I finished pulling the engine/trans out this morning and have been reading all day.
I have decided to stick with the l92 intake manifold.
Looks like I have two options:
1. Like jimmyg mentioned, i can look into the mast m-90 ly6 ss performance package (505hp)
2. I can get the vvt delete, get a nice cam (looks like the one in my initial post is a bit overkill for what i intend), some valve springs, and looks like i will need the ls1 to ls2 knock sensor retrifit harness and the cam position retrofit harness, and hptuners (or diablo sport).

Your biggest problem is going to be controlling the engine.
You either have to get a Gen 4 ECU and make that work with the rest of the truck, or use your stock ECU and buy a conversion box for the 58x and delete VVT.
