Need help with first 383 build

Hi everyone. I'm new to these forums, I hope I'm not out of place. I will be swapping a bigger engine into my 92 Firebird. I have a chevy 350( 1 piece RMS, non roller, I'm pretty sure 87-up) block, making it a 383 stroker. I have all the stock parts that came off of it, but don't plan on using any of the parts I pulled off. When I take the block to be cleaned and all, I'm going to have them bore it to 4.030" and hone it out. I'm trying to get 400 hp out of this build. I plan on hooking up a T56 6spd and 3.73 posi rear to this engine. I've been talking to some people about parts to buy, but would like to get some second opinions and more help.

Right now, I have a lunati 60103 cam and the lifters that cam with the 60103LK kit and a holley 4150 double pumper 650 cfm mechanical secondary carb. But I'm still figuring the rest of my build.

What I plan on getting:
Heads: Modified vortechs, assembled to handle .600 lift. 64 cc
Intake: Edelbrock performer rpm air gap
Pistons: Probe 12344-030 forged dish, compression dist 1.425", +20.40cc
Connect rods: SCAT 5.7" i-beam rods
Crankshaft: SCAT 9000 series, 3.750" stroke

I also plan on zero decking this, getting a CR of 9.45:1 with head gasket thickness of .040". Just wanted to get as many opinions and/or advice as I could.

EDIT: Cam:
