I'm not sure if the common rail gasket will work or not, but if not I would get in touch w/ Cometic gaskets (cometic.com). Maybe they would have a cure for you. I don't know for sure if they make Cummins gaskets, but they make MLS gaskets for just about everything else. I would also get a set of ARP's head studs while the head is off. They are definetly top notch, and a huge upgrade.
