What material are these exhaust gaskets made from?

These gaskets are made from EnCore HTX-900, a composite material featuring graphite-coated fiber sheets bonded to an expanded steel core. This construction is designed for high heat resistance and sealing performance.

What is the port size of these gaskets?

The port size for these Edelbrock exhaust gaskets is 1.813 inches by 1.75 inches. This size is intended to match the port dimensions on Edelbrock cylinder heads for the specified engines.

Will these gaskets work with standard exhaust manifolds or only headers?

These gaskets are suitable for both exhaust manifold and header applications. Their construction and recovery rate help maintain a seal even if header bolt torque is lost.

Product Details

If you're installing Edelbrock cylinder heads on your 1958-1965 Chevy 348 or 409 'W Series' V8, you'll need a solid set of exhaust gaskets to seal up those manifolds or headers. These Edelbrock gaskets are built for that specific job, ensuring a good seal even under high heat.

They're constructed from EnCore HTX-900, a well-built composite material that combines graphite-coated fiber sheets with an expanded steel core. This design offers good heat resistance and holds its shape well, which is important because exhaust headers can sometimes lose bolt torque. The material has a 50% recovery rate, meaning it can expand a bit if that torque loosens, helping to maintain a seal. The port size on these gaskets is 1.813 inches by 1.75 inches, designed to match up with Edelbrock's cylinder head ports.
