More info SOHC specific:
In general, advancing the cam timing (on a SOHC engine) lowers the speeds at which peak torque and peak power occur. Conversely, retarding the cam timing increases these speeds.
(N/A) Since we're talking about a Honda, I assume you'd like to get more power (@ a higher rpm), so retarding the cam timing by a little bit is probably the way for you to go.
(F/I) For forced induction, I would guess that the opposite is the case. My thinking is that you'd want to close the intake valve sooner, to prevent excessive blow-through.
