Fel-Pro 375-1424 Features:

Fel-Pro Performance Gaskets deliver reliable sealing under grueling racing conditions

Performance exhaust header gasket consisting of a high-density fiber facing material attached to both sides of a perforated steel core.
Resists blowout and burnout from high-temperature exhaust and is far stronger than basic paper gaskets.
Anti-stick coating permits motion without damaging the gasket and makes it easier to remove the gasket for future engine service.
Slotted bolt holes allow for easier header installation.
Not intended for use in emission controlled vehicles.

Fel-Pro Exhaust Header Gaskets come in varying levels of performance to fit any budget and driving style. All header gaskets are sold in pairs unless specified otherwise.

Fel-Pro Performance Gaskets: Consists of high-density fiber attached to both sides of a perforated steel core. The fiber has great torque retention qualities and these gaskets can even seal slightly warped surfaces and resist blowout/burnout from high-temp exhaust gas. A nonstick coating allows motion without damage, which simplifies gasket removal for servicing.

Fel-Pro Performance HTA Gaskets: Feature a triple-layer proprietary high-temp alloy (HTA) and coating to withstand up to 1600 degrees Fahrenheit. They have an embossed sealing bead that acts like a spring, maintaining a perfect seal under virtually any operating condition. A propriety coating ensures sealing over a broad range of surface finishes.
