Premium Copper Gasket Set for Ford Small Block SBF

YUCHENSHLP presents a 2-pack of copper header exhaust gaskets designed for rectangle-port SBF engines, including the popular 289, 302, and 351W variants. Constructed from solid copper, these gaskets resist deformation and stand up to heat, pressure, and vibration for consistent performance across sits and seasons.

Why choose copper gaskets?

  • Rigid copper composition supports a durable, stable seal under demanding temperatures.
  • Rectangle-port geometry helps create a tight, leak-proof interface.
  • Reusable design reduces waste and supports repeated maintenance needs.
  • No sealant is required when the gasket is installed correctly, simplifying the job.
  • Direct replacement option aligns with original port sizing, and two spacers aid installation.

What’s included

The kit contains 2 gaskets intended to refresh your exhaust system and restore proper flow characteristics. Two spacers are included to help you position the gaskets during installation.

Real-world use cases

Ideal for enthusiasts rebuilding a Ford SBF 289/302/351W or upgrading to rectangle-port headers. The copper construction offers resistance to wear from repeated heat cycles, while the square-port design targets a tighter seal across mounting surfaces.

Installation tips

  • Align the gasket with the port before tightening hardware.
  • Follow torque recommendations to minimize leaks; sealant is not required for these gaskets.
  • Inspect ports for debris and replace in matched pairs for balanced sealing.

Warranty and support

Factory-direct parts with a 100% warranty and United States customer support. If you have questions, contact YUCHENSHLP via Amazon for prompt assistance.
