cam degreeing needed?

It depends on what you want. usually you degree a cam if you want to change the Cam timing.
Otherwise it is only a check if the factory specs are correct.
So you will install it at 0 position.
2° advanced brings you a bit more torque from the bottom and if you retard it, it will bring a bit more power at the top end.

Examples:

Advancing:

Begins Intake Event Sooner
Open Intake Valve Sooner
Builds More Low-End Torque
Decrease Piston-Intake Valve Clearance
Increase Piston-Exhaust Valve Clearance

Retarding:

Delays Intake Closing Event
Keeps Intake Valve Open Later
Builds More High-RPM Power
Increase Piston-Intake Valve Clearance
Decrease Piston-Exhaust Valve Clearance


But i´m sure you will be fine with 0 position
