Exhuast Gasket SBC 913 Head

The Exhaust Gasket SBC 913 Head by Beyea Custom Headers is a precision-engineered seal designed for Small Block Chevy engines requiring reliable exhaust manifold-to-head sealing. This graphite gasket pair is essential for anyone restoring, rebuilding, or upgrading their SBC cylinder head assembly. Proper sealing at the exhaust port interface prevents costly gas leaks, loss of compression efficiency, and potential engine damage caused by uncontrolled exhaust escape.

Manufactured from graphite composite material, the Exhaust Gasket SBC 913 Head features a 2.060 x 1.900 inch oval port profile optimized for standard Small Block Chevy cylinder head castings. Graphite gasket composition provides excellent thermal stability and resilience under the extreme temperature cycling inherent to exhaust systems, where port temperatures routinely exceed 1,000°F. The gasket's oval port geometry ensures precise alignment with both 913-head casting ports and compatible manifold flanges, maintaining a consistent seal across the gasket face and reducing the risk of blow-by or exhaust leakage over multiple heat cycles.

Engine builders, restoration shops, and enthusiasts performing SBC head work benefit most from this gasket pair when installing headers, manifolds, or replacing worn factory seals. Compatible with all Small Block Chevy engines equipped with 913-series cylinder heads, the gasket ensures OEM-quality performance without the inflated cost of dealership alternatives. Installation is straightforward—position the gasket between the cylinder head port and exhaust manifold flange, torque fasteners to manufacturer specifications in a star pattern, and verify port alignment before final assembly. For best results, inspect mating surfaces for cleanliness and flatness prior to installation.
