The after market cam guys like Comp Cams advise advancing the cam timing by like 4 degrees for low-end power, and retarding the timing by about 4 degrees for higher RPM power. There is no magic power boost in fooling with cam timing in general. Most folks install new cams "straight up", meaning the timing marks on the cam drive sprockets are lined up like an overhaul manual specifies, as opposed to setting it up with a degree wheel etc, for getting all available power.
