Since I don't spin the motor over 6000 rpm and have .600 lift, do I need the titanium retainers? I don't have the problems listed in this thread - I have the CompCams Ultra Magnum rockers that have tons of clearance.
FYI - the springs are the AFR #8019 - 155# seat, 450# at 1.16, 0.650 max lift, 7200 max rpm.

No, use your existing retainers. 7K RPM would drive me to TI retainers. Your locks are tool steel.
