AV&V's Manganese bronze alloy allows you to fit the valve at a tighter clearance for better heat dissipation, longer life and quieter engine. They are all CNC machined and feature special Hi-temperature Viton O-ring to prevent oil infiltration between guide and head, tapered and radiused nose for easier installation and better air flow, a unique Super Grip valve seal section for use with either OEM style or Viton seals.
