Installation Notes: 428 Cobra Jet-sized valves promote excellent flow for streetable power; Rocker shaft stud kit #6009 provides better rocker shaft retention and is highly recommended for use with Edelbrock FE heads. It eliminates wearing of the threads and the possibility of bottoming the rocker shaft bolts in the head; Match with Edelbrock head gasket sets; 390 GT exhaust will not fit; Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using.
