It was after 1997 that I had a dealer tech tell me that if you wanted to get the good headgasket you needed to buy it somewhere other than the dealer. There's multiple vendors - Victor Reinz, Elring, Goetze? It seems to me that at least for a while only one of them was offering the reenforced version, so I think it depends a bit on who did the work and where they got the gasket.
