AV&V’s CNC-machined valve guides are made from Manganese bronze alloy which allows tighter clearances for improved heat dissipation, quiet operation and long life. Design improvements include a shorter top for higher lift and machined groove for a special high temperature Viton o-ring to seal the area between the guide and head, along with their ‘Super Grip‘ valve seal retention grooves to ensure the seal stays put. Tapered and radiused nose eases installation and raises airflow; guides are supplied with unfinished I.D., ready to be quickly sized using AV&V’s long-pilot carbide reamers. These reamers are designed to quickly finish-size guides when using AV&V Manganese bronze guides (not for cast iron guides) and AV&V valves – no honing required!
