I think 332 is the rear and 327 is the front. You should change both sensors while you're in there, and the wire too. The manifold "gaskets" are built-in the manifold.

My pleasure. Be careful routing the KS wire so you don't crush it under the intake. Also make an RTV "dam" around the knock sensors to protect them from moisture, and remove the square piece of foam under the intake (as stated in the GM TSB).
