Production breakpoint for improved M104 head gasket

Hi all,

Have been reading a lot about the M104 head gasket failures. I just changed the oil on my 1995 E320 (with 67k miles) and the head/ block interface shows no signs of leakage based on a detailed inspection from underneath the car. The car was purchased in Oct. of 1995 when the 96 models were already in the showroom. I was wondering if this car may already have an upgraded gasket but have been unable to find the information using the search function. Does anyone know when the improved gaskets were put into production?

Also, I have the same question about the M104 wiring harness.
