The Header Gskts Seal-4-Good SBC Square Port 1.5 provides a reliable sealing solution for automotive enthusiasts looking to eliminate persistent exhaust leaks. Designed specifically for Small Block Chevy engines, these gaskets address the common issue of flange warping and high-heat failure found in standard paper or composite seals. Whether you are performing a routine manifold upgrade or building a dedicated performance machine, these gaskets ensure a tight seal between the cylinder head and the header.
Constructed from multi-layered aluminum, the Header Gskts Seal-4-Good SBC Square Port 1.5 utilizes a dead-soft material that conforms to the unique irregularities of the mating surfaces. This design allows the gasket to compress into gaps, creating a permanent seal that does not shrink or blow out under extreme pressure. The square port configuration is optimized for high-flow exhaust systems, ensuring that there is no restriction in the transition from the engine to the headers.
These gaskets are sold as a pair and are compatible with 1.500-inch square port Small Block Chevy cylinder heads. When you buy these for your next project, you benefit from a reusable design that maintains its integrity even after multiple heat cycles. Review the technical specifications to ensure compatibility with your specific manifold flange before installation to achieve the best results for your vehicle.
