upgrading to 2 10mm outside exhaust studs?

The problem with SS studs is the expand to much from the heat and can loosen up on you. They do sell SS studs with a jam set screw to help hold things together. The mild steal stud is more suited for the thermal growth of cast iron manifolds and aluminum heads. But the SS studs are shiny and do work for most people.
