"Swift" valve springs

Looking for comments, experiences, or other information about "Swift" valve springs.

Made by the same companies that make Porterfield, Hawk, Raybestos, Performance Friction brakes, Redline Oil, Tilton master cylinders, etc.

Claimed to be a new metallurgy with a carbide formula. Stiffer and more resilient than traditional steel, thinner wire, fewer coils, less weight, more force.

Can anyone verify these claims? Can they be used in 911 engines?

Thanks:)
