Intake/throttle body help

I have a 06 hd2500 chevy that I just built a 408ls, prc heads, 11.1 ect. I need help with what throttle body, intake, fuel pump/pressure I need. I already have 60lb injectors for it. It should make around 500hp.

The NNBS intake would work. Otherwise you could go aftermarket and spend big dollars but I don't know what you are after for budget/looks etc.

A single Walbro 450lph pump would be plenty, then an aftermarket regulator. Keep the fuel pressure are 58 psi.
