the HEI eliminates the nutter. all you need is a basic vacuum system like in the link I posted. I have the same setup as you with the 390 holley. the only vacuum line in your pics that I have is the one coming out of the intake, it goes to the heater control in the cab. I did away with the others you show as they are part of the old emission system.
the other lines I have are the PVC line from valve cover to adapter at the base of the carb.
vac line from manifold to brake booster. vacuum line from carb manifold vacuum port to distributor, thats it.
you might also have the vapor canister, ( I don't ) the vacuum lines for it are shown in one of the diagrams.
