Viton® Valve Seals

These valve seals offer additional clearance between the seal top and the bottom of the valve retainer over the stock valve seals. This allows you to run high lift cams, or high ratio rockers without the need to machine down the top of valve guide post. Vitron® (DuPont) offers excellent heat resistance (-65°F/-58°C to 400°F/200°C) and excellent resistance to aggressive fuels.
