Hi,
sorry to hear that the gasket seems to be broken. The good thing is that it's not voodoo to exchange both of the gaskets and you could use the chance to also exchange the valve stem seals and all the oil seals in the heads and the timing belt as well - then you are happy for the next 60k miles!
But more interesting should be WHY a gasket failed, as this is really unusual on the V8 3,6 engines. It would be really bad luck if you repair everything and some weeks later you've the same problem again.
If you need anything, like part lists, please let us know - we'll support you wherever possible!
Best regards
Bastian
