    Has anyone had any improvment in spring life by cryogenically treating valve springs?

    For as cheap as they are I don't believe you'd see any value. If you own the cryo equipment then sure...-300 below stuff to death...otherwise...recycle recycle recycle

    We used the Cryogenic treatment on a crankshaft.
    It reduced the flexing and wind up making the #2 and #4 main bearings life double.
    Not too sure you want a valve spring to be denser - thereby reducing the flexing and wind up.
    Those Metallurgist guys are pretty sharp between the ears I would not go messing with their stuff with out a BIG budget for testing. A broken valve spring can really hurt an engine.
