Which knock sensor am I suppose to go with? They are listing a late production and just a normal one.....

Is this a revision to it?

Depends, my rear sensor had oil the the well so I needed the well plugs and the valley gasket too. While I was in there I replaced the wiring harness that goes to both sensors and out under the manifold.
