I am in the process of installing my new LS1 but have a few Q's.

First the the coolant vent tubes that sit on top of the oil valley. The head gasket kit that i got from cmotorsports gave me blockoffs for the holes that go into the head at 4 diff spots. Do i just block them lines off? They end up going to the throttle body which i have bypassed anyways?

Then on the LS1 block there are threads for a coolant hose or something on the drivers side towards the front. What in the hell do I do with that? Do I just plug it or is there something I need to reroute to go there?

 

you can put the blockoffs in the back. but then you will need the front crossover from a camaro. i have never seen someone block off front and back.

and your second ? i cant remember what you are talking about maybe be more spacific on were it is at.

 

The hole near to front of the drivers side head is for the coolant temperature sensor.
