Does anyone know if you can adjust cam timing?

Is it possible to adjust the cam timing for more RPM or more torque? How about the ignition timing? Do you just leave it straight up or can these be tweaked for a little more juice? This is for 83-85 200x. Does anyone have any thoughts? Thanks.

Dennis Kirk was selling cam sprockets that had a whole bunch of holes in them and they said it was for tweeking the cam timing. I suppose you just rotate the sprocket with the cam bolts out until the next set of holes line up and install bolts. I dont' see what this difference would be rather than just having the timing a tooth off?

by advancing the cam timing it increases low end and retarding the cam timing increases top end. however, piston to valve clearance becomes a problem. the valve could possibly hit the piston.
