This is usually done to high performance heads to increase the fuel/air flow into the cylinder. The radius over the edge of the valve is much smoother so air flows past it easier. The latest is a 5 angle cut. Of course to see this improvement, you need to be up in the 5000 - 6000 rpm range and are probably drag racing or doing the NASCAR thing or have a hot street rod. This would be wasted money on a tractor.
