does annyone know if the 1995 s6 came with metal head gasket cause my motor had regular head gasket and the g60 corrado came with metal headgasket,and since it is vw/audi I was wandering if audi s series came with it too.

yes the Audi AAN and ADU(RS2) came with factory steel headgaskets

Not 100% true. The early AANs came with a paper and steel headgasket. The later cars (somewhere in the UrS6 run) came with the all metal headgasket. All the factory replacements are all metal now.
