Stock Valve Spring Retainers

Can the stock aluminum valve spring retainers handle aftermarket higher tension valve springs. I overheard that the aluminum retainers are just fine for the stock valve springs, but with aftermarket springs the valve keepers will begin to sink down in them.
$200.00 for the titanium retainers and are they necessary.

Please advise.

Stock retainers are fine, the titanium retainers are not necessary unless you are adding big cams, the ti retainers will give more clearance.
 
Ti retainers are a waste of money. They are known to spit shims. Ti is heavier than aluminum. The stock retainers are fine.
