Ford Windsor Copper Embossed Exhaust Gasket

The Ford Windsor Copper Embossed Exhaust Gasket (part number 4036) is a professional-grade copper gasket designed for Small Block Ford engine exhaust systems. This pair of rectangular port gaskets measures 1.200 x 1.470 inches and delivers reliable sealing for header and manifold applications where thermal cycling and combustion pressures demand superior gasket performance.

Copper construction provides several critical advantages for exhaust gasket applications. Copper's superior thermal conductivity allows heat to dissipate more efficiently than softer materials, preventing gasket degradation under extreme engine temperatures. The embossed design increases surface contact and gasket bite, reducing the likelihood of exhaust leaks at the header-to-manifold interface. For Small Block Ford engines operating at sustained RPM or in high-performance applications, proper gasket selection directly impacts exhaust scavenging efficiency and engine reliability.

This gasket is engineered for engine builders, restoration specialists, and enthusiasts rebuilding or tuning Small Block Ford powerplants. Whether replacing worn gaskets on a classic engine or assembling a fresh short block, the rectangular port design and copper composition ensure consistent sealing across multiple heat cycles. The pair format accommodates dual-exhaust configurations common in performance and restoration contexts.

Exhaust gasket failures often go unnoticed until power loss or overheating develops, making gasket selection during assembly critical. Copper gaskets resist the sulfur compounds in combustion byproducts better than composite alternatives, extending service life in high-mileage or modified engines.
