I am going to put an LS6 intake on an LS1 motor. I got the parts from General Motors one crossover pipe and two plugs. My question is this: Where do you put the two plugs in the back of the motor or in the front of the motor? Does the crossover pipe go in the front or in the back? Putting plugs in the heads, will this slow down the coolant or make heads run hotter? Hotter than normal? Thanks for all your help.

Plugs go in rear; crossover goes in front.

Could get an extra crossover and put it in rear (instead of plugs)...

and then plumb hoses from front and rear crossovers to a brass Y which then goes to radiator neck.
