Actually retarding the cam 4 degs does lower your torque by a few points, but the higher end HP gained is sometimes well worth it on cams with a duration in between the 240-265 range.
To the best of my knowledge, advancing
the cam timing 4 degrees will lower
when the torque curve begins by about 200 RPM. This will yield more bottom end.
