Do I need to reuse the fulcrum rocker guides on Roller rockers?

[Lxpony]

putting on new heads and FMS 1.6 RR- the stock stamped steel rockers have the fulcrum guide metal bar thingly that connects from the ped on the exhaust and intake sides- do I need to reuse these when installing rocker rollers??

If your heads are pedastal mount, then yes. They align the rockers, and retain the pushrod geometery.
