Mike:
No one around that's a "certified" Superformance shop. Nearest is, I think, in Idaho.
Locally probably Dana (see earlier post on this thread) would be your best bet for advice.
You might also try the Superformance Owners Group here on CC if you have particular questions. I'll ask around at the Cascade Cobras club meeting in a couple of weeks as well.
