Would advancing this cam 2* or so be worth doing.

I have the engine out of my car at the moment doing some maintainance and changing up a few other items. I have the timing cover off at the moment and am going to degree the cam, it wasn't done back in the day when the engine was built. My question is would it be worth it to advance this cam 2* or possibly 4*. What would change? Would the powerband change? Would the idle change? Should I try 2* or 4*? Or should I just 0* the cam at 112 like the card says and put it back together?
