AV&V Parts & Accessories

AV&V make one-piece forged valves and matching valve guides for Harley-Davidson engines — racing-grade stainless steel with bearing-quality hardened tips designed to handle high-lift cams without premature wear. The manganese bronze guides are CNC-machined for tighter clearances and better heat dissipation than standard. Coverage spans Twin Cam, Milwaukee-Eight, Evolution, Sportster, Shovelhead, and Panhead.

If you're building a performance cylinder head, AV&V is the name that serious head builders use.
