    These superb valves feature the highest flow level on the market. They are one piece forged from a racing grade stainless steel alloy. Each valve has a bearing quality hardened tip to prevent premature wear with high-lift cams.

    AV&V’s 5/16 stem valves also features a 45° angle below the lock groove to facilitate valve seal installation. Each valve is heat treated with a special process and their stems centerless grinded to a micro finish for longer life.
