I have a fair understanding of mechanics but was not aware of the "ball studs" in the mercedes model heads. I believe your advice is right on.

The 380SL only has 82,000 original miles and was my father's. I get sick inside everytime I hear that engine noise. I'll read the other threads carefully to ensure I do the job right using the recomended tools and methods.

Thanks again. I see you have been a great resource to many others as well.
