Livernois Valve Springs

[DOHC otto]

Has any 4v guys used these, they claim the following,

No added cost for special retainers, spring cups, or seals
No machining necessary
Designed to work with all factory hardware
Give added spring pressure needed for any aftermarket camshaft
Eliminate valve float to reduce the risk of any engine damage in high lift or RPM applications

Anybody use these ? Good product or junk ?
