Header Gasket Set - SBC D-Port 1.750 x 1.600

The Header Gasket Set - SBC D-Port 1.750 x 1.600 is a precision-engineered exhaust header gasket pair designed specifically for Small Block Chevy engines that require reliable sealing at the cylinder head-to-manifold interface. This gasket set is ideal for engine builders and performance enthusiasts who are assembling or rebuilding small block Chevy engines.

Constructed with a composite material that combines rigid support with flexible sealing properties, these gaskets accommodate thermal cycling and vibration without degradation. The D-port geometry matches the exhaust port configuration of most SBC heads, ensuring proper alignment and consistent clamping load across both cylinders. The gaskets are designed to resist oxidation and maintain integrity across repeated heat cycles, making them suitable for both street and performance applications.

This gasket set is particularly beneficial for those working on classic or modern small block Chevy builds, including engines with D-port head castings. The design maximizes seal surface contact and minimizes blow-by at the gasket perimeter, ensuring optimal performance. Whether you are restoring a classic vehicle or enhancing a modern engine, this gasket set is a reliable choice for maintaining exhaust integrity.
