No, I have a complete set of Metric tools (look at the bottom of this message and see what else I drive--you'll understand why) and I think it was a 10mm or a 12mm. Don't quote me on that though. Two or three of the bolts are longer than the others. Make sure you remember where they go when you pull them out--don't strip the threads!!
Also make sure you clean and dry the gasket mating surfaces before re-installing. I would either use some brake cleaner and a dry, lint free cloth. That would be the safest. Also check the torque specs and torque the bolts correctly. Don't over-torque are you will spring a leak.
Good luck and enjoy the honeymoon
