Hey, there. You probably figured this out, but this questions should be posted in the Engine help section not the How-To.

For what it is worth, I replaced the knock sensors on my 04 Suburban Z71 with the 5.3L. I think your 6L motor is similar. Check out the procedures documented over on the Z71Suburban-Tahoe forums at:

http://z71tahoe-suburban.com/iboard/ind ... owforum=12

Follow the 2-part instructions Pinned at the top for Intake gasket replacement. You have to take off the intake manfold to access the knock sensors, which are shown in the last few steps.

You could also check my photo how I sealed up the covers to minimize the potential for future flooding of the sensors:

Here is what the rear sensor looked like compared to new:
