Bought these used from SonicBlue03L in a package deal with some stage 2 cams. Going a different route and bought a set of heads with valves and springs, so i wont be needing them.
Was told they have 1500-2000 miles on them and I see no reason to believe otherwise.
Part number 84706
From DRI's site
Kit Includes:
16 High Pressure Valve Springs
16 Steel Retainers
.620 Maximum Lift
