Need help with vacuum lines

[phillipjfry]

Hi,

Pulled my intake manifold off to replace my PCV. I keep hearing to replace the vac lines while I'm in there. But I dont see any... all the ports are plugged on my manifold. There was one 2" degraded vac line that I replaced, but that's it.

Please help.

Also I'm replacing the hard coolant lines, coolant sensor in the block, and starter under Mafia suggestion.
