Valve Seat 2.450 x 2.090 x .375

The Valve Seat 2.450 x 2.090 x .375 from DART is a precision cylinder head component engineered for high-performance engine builds and competition applications. Whether you're rebuilding a stroker motor, refreshing a tired engine, or assembling a race platform, this valve seat delivers the exact dimensional tolerances required for proper combustion sealing and thermal management. Engine enthusiasts and professional machine shops rely on DART valve seats for their consistency and durability across thousands of operating hours.

This valve seat is precision-manufactured to exacting specifications, with a 2.450-inch outer diameter and 2.090-inch sealing diameter that ensures a perfect fit in compatible cylinder head bores. The .375-inch thickness provides optimal material density for heat dissipation and structural integrity under peak combustion pressures. DART's manufacturing process delivers true concentricity and surface finish quality that promotes superior sealing against valve faces, reducing blowby and maximizing compression retention throughout the engine's operational life.

This component is ideal for small-block and mid-sized engine platforms where precision valve seating is critical for performance and longevity. Installation requires proper bore preparation and alignment tools—most users benefit from professional machine shop fitting to achieve factory-correct valve seat angles and run-out specifications. Verify your cylinder head's valve seat bore dimensions and angle specifications before ordering to ensure compatibility with your specific engine platform.
