Although the information states 1996, I believe that the motor may have been switched for the 95 or al the least the heads were changed for whatever reason. My clue was that whenever I would want to change the spark plugs the ones listed for the 96 were not the ones that fit. The plugs from the 95 had the proper length and thread depth and pitch.

So here is my dilema... Do I gap the plugs as if this was the 95 motor or do I gap the plugs for the specifications of the 96 ECM?
