I've run them two years with Jun2 cams, portflow/ITR springs, no problems to report, max revs 8600. I've seen guys with broken Jun retainers, so it can happen to any brand , although I've never heard of a Toda one going bad.

No they don't. My reccomendation is Ferrea

Portflow or Ferrea ti retainers

It has long been understood that Titanium is both stronger and more brittle then steel. As a result, they are far more likely to develop stress fractures and crack vs. their steel counterparts. True they are lighter and will allow the valve train to run faster but I think it would be prudent to stick to a strict replacement schedule if you want to ensure long engine life. Remember that no engine has ever survived the failure of one of it's valve spring retainers!

I know it is not uncommon for some race teams to replace retainers (steel or titanium) after every race!

Personally I don't feel the risks are worth the rewards for a daily driven machine. Consider for a moment the fact that neither SPOON, TODA, nor MUGEN offer Ti valve retainers... WHY is that?

Titanium also likes to gall badly. titanium is not all it's cracked up to be... mostly a mislead public thing.
