I've got a problem with my roller rockers not clearing the springs on my heads and they are wearing grooves in the rockers
. The heads are a set of Dart Pro 1 230cc heads with 3/8" screw in studs and the springs are 1.550" o.d. and the rockers are a new set of Crane Energizer 1.6's for a sbc.
Does anybody know a set of rockers that will clear the springs? I got on the dart website but didn't find any answers.
