Valve Seat - 1.650 for I/E Head

The Valve Seat - 1.650 for I/E Head (DART model VS1650) is a precision-engineered engine component designed for intake and exhaust valve applications in high-performance and rebuilding scenarios. This powdered metal valve seat is essential for engine builders, machine shops, and motorsports enthusiasts who require reliable sealing surfaces for optimal combustion chamber integrity. Whether you're restoring a vintage engine, upgrading a competition build, or performing a complete cylinder head overhaul, this component delivers the durability and precision fit that serious engine work demands.

Manufactured from powdered metal, this valve seat features a 1.650-inch outer diameter (OD) with a 1.250-inch inner diameter (ID) and a 0.350-inch height, engineered to precise tolerances for consistent seating surfaces. The powdered metal construction offers superior hardness and wear resistance compared to softer cast materials, preventing erosion from repeated valve cycles and high exhaust temperatures. The compact 0.07 lb weight and compact 1.8 x 0.75 x 1.95-inch dimensions make it easy to handle during installation while maintaining the structural integrity required for reliable long-term performance in demanding engine applications.

Engine rebuilders and performance shops benefit most from this DART valve seat when conducting comprehensive cylinder head work or addressing worn seating surfaces that compromise combustion sealing. Installation requires press-fitting into prepared valve seats within the cylinder head, making precision machining and proper tooling essential for correct alignment and interference fit. This component is sold individually, allowing technicians to replace damaged or worn seats while maintaining original specifications or upgrading to improved materials during major engine rebuilds and restorations.
