Vacuum Lines Under Manifold - HOW?

They are a b**** to get to. When I had my upper off to smooth and paint it, I installed it back on, had EVERYTHING hooked back up and realized I forgot the very bottom vacuum hose...needless to say after a few choice words, I took it all back off and put the hose on (a very nerve-racking thing when you are working with a freshly painted intake).
