head crossover vapor pipe Hey guys, im building a gen III motor from scratch and need the skinny metal tube that goes UNDER the intake manifold and CONNECTS to the heads in the front and back of both heads. It looks like it is about the size of a brake line. I have contacted the dealership but they are cluless to what it is, im sure somebody on here knows what it is. If anyone could tell me the real name of it, where to find it or the GM part number i would greatly appreciate it.

its a coolant crossover pipe.
You have 2 choices (you are better off getting a LS6 pipe and 2 of the rear block offs so you can put on a LS6/LSx manifold in the future (they will not fit with a standard LS1 coolant pipe)
Either:
LS1 coolant crossover pipe = 12562169
-or-
LS6 coolant pipe (01-02) (need for installing LS6 intake manifold) = 12568478
LS6 coolant plug (01-02) (need 2) (need for installing LS6 intake manifold) = 12562788
