Default Vacuum port

I have an elderbrock performer manifold and Holley 4160. Problem is, there is one port which was hooked up to the brake booster(engine came out of a no-flip headlight car)...I am assuming I can replace that valve with the one that came off the car originally(for the headlights) but the Carb does not appear to have a port for brake booster...what would be a good way to hook up the booster?

4160, but GM intake. I T'd the brake booster to the EGR port as that's the only port available on that carb. Don't know if it's good or bad but the holley installation manual said so. Do you have a intake vacuum port for light's and heater control?

Yes I have the vacuum port valve that goes into the intake for the lights....good idea on the brake booster hose..didn't know you could do that and I don't have a manual for the carb. Thanks!

I am going by memory here but LT-1's have Holley's and the power brake boosters get their vacuum from the intake port.
