Clearanceshould also be checked between the rocker arm and valve spring collar, as well as between the rocker arm and rocker cover. It is imperative that the engine builder confirm these clearances and checkfor spring coil bind, even when using parts specifically designed for high performance. Most valve train failures can be traced to over-revving or failure to confirm correct clearances during assembly.Dealer Services& Promo ItemsWarranty &Company PolicyOEM Cross ReferenceAppendix & IndexVisit us at www.sscycle.com4-37
