Kevin,
I've been in your situation. Summit can get the SS header bolts for you but it has to be custom ordered. They are not cheap. A set will cost over $80. I ended up buying mine from DC performance for the same price. I figured I'd buy it from a Viper vendor to keep it in the family so to speak. Here is the link.
