Salsa do a range of high rise stems.
You got get them from any shop that deals with Ison.

Specialized?

Are you sure you want a high rise 70-80mm stem though. Don't forget the effective length compared to 'normal' 5-7 degree stems will be much less especially with rises as high as 25 degrees (or more)
