If you are going with the 272 duration set or lower, your stock springs and retainers will be fine. The lift isn't anything to be concerned about. When you start breaking 10.5mm of lift, then yeah, go to the solid lifters. Hell, DSMs rev to 8k consistently on their rocker arm setups without floating valves on HKS 272s all day long. But really, at anything higher than 272s, you better be running a ported head and sheet-metal intake manifold so those aftermarket springs and retainers should already be done...
