Without generalizing too much, on my street engines I pick the intake duration for where I want peak power, use a closer LSA (108* or so) to get more mid range torque and add a few degrees exhaust duration to extend the power band. This gives me good torque and power over a wide RPM range, perfect for a performance street engine.
