If you degree it, then you can advance it.
Once you have it degreed, then make sure that it is installed at spec (0° advance from your degree info).
Then decide if you want to advance or retard it and use one of the offset keys for the cam to bump it a degree or two where you want it to go.
Then degree it again to verify that it went where you intended it to go (and not in the opposite direction).
