I'm pretty sure that they run it super lean in partial throttle conditions which would increase combustion temps significatly, but with better cooling, would run not damage the motor. All the while using regular gas, to make it cheaper for the consumer.
I'm sure that subaru has torture tested the motor (or are currently doing so) and i doubt they would release it with an issue like blowing up headgaskets (They're not Chrysler after all). I'd be more concerned with anyone trying to boost this motor. Seeing as how between the "improved cooling" and "same size more displacement" lines I can read "thin cylinders walls with an open deck and water jackets everywhere"
