Fel‑Pro 1421 exhaust header gasket set pairs high‑density fiber facing with a perforated steel core and anti‑stick coating to resist blowout and burnout while allowing thermal movement. The construction is stronger than basic paper gaskets and slotted bolt holes help during header installation. This gasket is intended for performance header applications and not for emission controlled vehicles.
