Description

The DART SBC Exhaust Valve 1.600 x 8mm - 4.940 OAL is a precision engine component engineered for small block Chevrolet cylinder head applications. Designed for builders and machine shops seeking reliable OEM-quality valve replacements, this exhaust valve handles the thermal and mechanical demands of high-performance and stock engine builds. Whether you're performing a complete head rebuild, upgrading worn valvetrain components, or assembling a performance engine package, this valve delivers the dimensional accuracy and material integrity required for dependable operation.

Constructed from stainless steel, the DART exhaust valve features a 1.600-inch head diameter and 8mm valve stem, providing optimal flow characteristics for exhaust gas evacuation while maintaining structural integrity under sustained combustion pressures and thermal cycling. The 4.940-inch overall length ensures proper seating depth and clearance in small block Chevrolet cylinder head bores. Stainless steel construction resists oxidation and corrosion, extending valve life and maintaining a reliable seal against the valve seat across thousands of engine cycles.

This valve suits engine builders, cylinder head reconditioning shops, restoration specialists, and performance enthusiasts working on small block Chevy platforms including 262, 283, 302, 327, 350, and 400 cubic inch variants. Installation requires proper valve seat machining and spring pressure verification to ensure correct installed height and sealing performance. DART components are manufactured to stringent specifications, making them an ideal choice for both stock rebuilds and modified engine applications where reliability cannot be compromised.
