Stop in for a cup of coffee

Hey, folks!
Trying to find old cam specs isn't all fun and games. I've got two I need to choose from.

I've managed to find one, Sealed Power CS-140R. 218/218 degrees @0.050" 0.444"/0.445" lift.

The other one has the rather odd name s725. The only other info I have is 268 degrees, 0.450" lift.

Does anybody recognize the style of designation from any brand of camshafts?
