  • Upgraded Oiling System: Has a complete stock-type system plus a low-tension priority main oiling system with front and rear external oil pump feeds.
  • Dual Crossovers: Allow oil flow to be metered with restrictors for roller lifter cams and/or roller rocker arms to reduce oil flow and windage.
  • Reinforced Head Bolt Bosses: Blind-tapped to prevent leaks and produce accurate torque readings. Extra-thick decks prevent head gasket leaks.
