If you look around the valves, where they are closest to the edge of the combustion chamber, he removed a bunch of material, in the corners kind of. it will help airflow. especially at low lift times. so when the valve opens, air all around the valve gets to pour into the combustion chamber instead of just the areas that are "open" to airflow.

If you look at the after picture, supersized, you can see the shiny spots on the corners of the valves where he removed the material.
