Well I noticed that the LS6 coolant tubes, the ones that cross over from one head to the other, have o-rings on them, while the stock LS1 coolant tubes dont. So are you guys still using the coolant gaskets/seals(12551933)? I'd imagine not, but I'd like to see what others are doing. I am planning on running two front LS6 coolant tubes in case you were wondering.

They switched to a new design. The old design was just the tube with flat gaskets....the new style has rubber o-rings that come with the tube.

Is it just me, or do the LS6 caps (rear) look crooked because of the oring when they are installed?

I don't know. But don't forget to block off the holes in the back of the heads. And do it before you install the heads!

yup redesigned about 6-8 months ago . all the new tubes and block offs use orings now .

I'm using two front coolant tubes, one in the front and one in the back to help keep the back cylinders cool also. The motor is out of the car so installing these is no feat.
