I just replaced the head gasket on my 300TE. A couple of the bolts were questionable, so I went over to the mercedes dealer to get some replacements.

While purchasing these bolts, I was told I also needed "stretch washers", so I bought 14 of those pricey little guys.

Now I am confused? How come I was told I need these washers, if there are not any of these washers on the head in the first place.

Is there something I am missing here?

As always, thanks!
