I went to the www.headgasket.com site JasonESi_T mentioned :-), its a $100 for the gasket, problem is he makes them whatever thickness you want, so he doesnt know the stock thickness. I have a factory manual and I can't find it anywhere. I called the dealer they don't know either. If anybody knows let me know, otherwise Ill have to take a micrometer down to the dealer and measure one.
