Roberto,
The Conn you have uses a 120 degree valve, not the easier to reverse 90 degree valve. The only person I knew who could reverse a Conn was the late Walter Lawson who charged $300 for this service to a member of the New York Philharmonic in the 1970's. Sadly he must have taken this knowledge to his grave. I suppose someone out there could make and install a new valve for you.
