Vacuum Rebuild

[88YJ6]

Ok so I need to put in a new exhaust manifold gasket, which looks like a bundle of joy to do: draining the radiator, pulling air intake, carb, intake manifold, exhaust manifold.
So my question is would it be worth it to re do the entire vacuum system that deals with the carb when I am doing this? I already have one hose that doesnt go anywhere and not really sure where it is supposed to go and some valve or something that had the vacuum nipple broken off, so my idle sucks...besides having the carter.

Thanks guys

I would replace all the vacuum lines, one at a time. They get old and dry rotted, and collapse on themselves easily.

Just get an Oreck.
