LS6 coolant rossover pipe: 12568478
LS1/LS6 steam pipe plugs: 12562788

I'd personally run two of the crossover pipes, one in back and one in the front, this way the back of the heads get cooled also. Just run a piece of 1/4" coolant hose from the back crossover to the front, and use a T-fitting to connect it to the front pipe. This is what I did on my 427 and it worked awesome!

Just grind down the bottom ridges on the ls6 intake and forget the coolant lines.
