One nice side effect of the beehive spring is that the steel retainer is smaller in diameter and therefore is lighter, so there's less unnecessary metal going for a ride on top of your valve spring. That takes some load off the entire valve train. In NHRA Stock Eliminator, practically everybody use them and we use 10 degree valve locks. We use spring pressures that aren't found on the street, most of our spring pressures on a small block are around 180-200 on the seat with 360-400 over the nose. We're restricted in cam lift by class rules, but these engines will turn higher than we need them to with that set up. Lighter and stronger is always better.
