I would run a few gallons of the higher octane fuel, it will help keep deto under control.

Even though the SVT is tuned for 91 or higher when you start doing extended runs (20+ minutes at a whack) the heat generated during that time can most definitly cuase you to experience some deto (be it ever so light and you may not notice it) and the higher octane fuel should allow you to keep running the maximum spark advance (more power)
