your wrong.
Higher lift HELPS but duration is what actually "breathes" more at higher rpms.
low duration with high lift equals a lot or torque, high duration with low lift equals more top end power.
almost all the time. there are variables in tuning of course.
There is also a law of deminishing returns with cam sizing. If you go too large on lift (over 12.-12.5 mm) you just are not getting any more efficiency out of the head (most nissans at least).
11.5-12.0 is the largest I would go with stock displacement and stock valve size.
