The Fel‑Pro 1664-1 valve cover gasket set uses composite material laminated over a steel core for high compression and torque retention in extreme vacuum conditions. Developed for high‑load race applications such as Pro Stock and Top Fuel, this gasket set is not intended for use in emission‑controlled vehicles. It’s built for consistency and strength where repeated service or high temperatures are expected.
