A wider seat transfers heat from the valve head to the head better. GM uses a single cut, the head is 45 degrees and the valve is 46 degrees, a three angle valve job will add horsepower over this arrangement and will give acceptable life, but the GM single cut will last longer. Honda uses a three angle on all of its engines, and gets maybe 250,000 miles out of a valve job. With a high quality valve, such as a Feria 6000 series, or Manley Pro-Flow, it doesn't seem to make any difference how many angles are cut.
I'd go with a three angle for the street and using stock valves.
