I reached out to GXPtuning as suggested above. He provided a suggestion for cam, DOD kit, oil pump and torque converter but said I would have to find a local tuner. Assuming I understood correctly..
Correct he does not do remote tuning. PatG is familiar with his cams/builds. Matt has a stellar reputation on LS platform.

I got my kit from BTR. The heads, if you can afford the extra.... idk $1.5-2k for "nice" heads I would do it. Cam, intake, headers with a tune will give you close to 150 hp. If you don't have the cash to buy heads, consider having them ported.
I paid $300 to have a local shop mill, clean my heads and seat my new LS3 intake valves. It wasn't worth it to me to buy new heads and intake. I'd put that money towards a LSA instead of the latter. Don't mill the heads if you want to do boost later...compression too high.
