The Header Gasket - LS1 Stock Port by FEL-PRO is an OEM-spec replacement seal specifically engineered for LS1 engines with factory exhaust manifold port configurations. This gasket is ideal for those rebuilding a stock LS1 engine, restoring a fourth-generation Camaro or Firebird, or maintaining a truck platform powered by this legendary small-block. It effectively prevents compression loss and exhaust leakage at the critical manifold-to-head interface.
FEL-PRO's reputation for precision gasket manufacturing ensures that this component meets or exceeds original factory tolerances. The gasket is designed specifically for LS1 port geometry and is made from advanced elastomer compounds with steel core reinforcement, allowing it to withstand sustained cylinder pressures and thermal cycling common to street and mild performance builds. Its compact profile, measured at 0.45 inches thick, is intended to provide effective sealing, although head resurfacing may still be necessary in some cases.
This gasket is perfect for anyone replacing factory LS1 exhaust manifolds during engine maintenance, headwork, or troubleshooting persistent exhaust leaks. It is compatible with all LS1 variants and direct-bolt aftermarket headers designed for stock port LS applications, delivering the reliability needed without exotic coatings or excessive costs.
