We are adding a gasket to hold part to get a better measurement. It is not a gage, so how must to add to our quality sytem; would it just be a jig? Do we need measurements on the gasket itself or do we perform gage rr?

I will start with clear definitions:
  • Fixture - used to secure, support and locate a workpiece
  • Jig - used to secure, support and locate a workpiece AND guide/locate a machine tool
You appear to be describing a measurement fixture. You do not need measurements on the gasket itself, but you should perform an R&R study on the entire measurement system, which now includes the gasket. After all, the reason you added the gasket was to get a better measurement. A gage R&R should confirm that you actually did achieve that goal.
