On a 7.2 car, the 'Actual angle for camshaft' should either be 0 or 25 depending on whether the solenoids are activated or not activated. The cam shaft variation on these early cars is either all or nothing. Only the later cars (7.8DME) had the ability to regulate the actual value of advance which can give values between 0 and 40 depending on condition.
As stated above, 9 degrees base timing means your cam timing is out of spec.
