I would tend to agree that you could use a new set of rockers do to metal fatigue if you are runnignin with the original rockers. A set of the HD stamped (I run consistamt 11.40's with them) with your push rods or a set of 273 or other doctile iron rockers and push rods for a hydraulic cammed engine with adjustable rockers will sork just fine. DON'T Go with the elcheapo eBay type rollers to save a buck. Good rollers are spendy and I have seen them come appart.
