vacuum line diagram

I have a 305 V8 engine with Rochester 4 Barrel Carb.
Most of the vacuum ports are closed. I want to re-use all vacuum ports and for that i need to know where these ports connect to engine peripherals.

Any diagram to show and describe vacuum lines?

Re: vacuum line diagram

thank you very much. Many carb diagrams but what do i need to know for my carb to choose the most appropriate?
Rochester 4bbl is an 82 year carb ? So do i choose the 82 carb diagram?
If i look for a code in carb surface maybe i can find out year it had been manufactured?
