you chure? if i'm at .15 in the exhaust, shouldn't i go with a smaller shim to loosen the valve?

Follow the proper procedure and adjust your valves accordingly. Don't worry about 175psi compression, it's fine.
Worry instead about running your bike with tight valves. If they can't close all the way, you can, and will burn them.

All the the higher compression #'s indicate is a build up of carbon. Is your bike running rich? That's a good way to build up carbon.
