when you degree a cam you are just double checking that it is the same on the cam card. depending on your setup you can advance or retard the cam to suit your needs.

Like Adam5.0 said, most people check to make sure the cam was ground per the specs by degreeing the cam and adjust to install it straight up. Advancing or retarding the cam timing shifts the power curve up or down the RPM band. Advancing makes more low end power, but top end suffers. Retarding is the opposite, it makes less low end power but the top end it'll make more power.

What is your goal?
Nice street combo? Go straight up or advance it 2*.
Nitrous? Retard it 2*
Either way the power band will shift about 300 rpm.
Advancing will be a bit more peaky, building power more quickly but falling off more rapidly after peak
Retarding will make the power band more broad.

With a mild n/a setup I would install it straight up just for the all round power and street drivability. Just pay close attention to your fuel press. and timing.
