1986 Chevy Truck rebuild engine?

I a currently wanting to rebuild my 454 big block chevy. The problem I am having is while I want to remove my emissions controls on this motor. I need help with what I have to keep to have the motor run correctly. I am running a vacuum advance and do have a th400 with vacumm modulator. I am changing the intake. Carb, and exhuast. I am going with a non-egr maniforld and an edelbrock 800cc avs carb. If you could please let me know this infomation that would be great. Oh one more thing I have hydroboost brakes, does this set up run any vacuum lines like the power brakes boosters do or does it just use the power steering pump to make the pressure? Thanks very much.
