Valve Seat - 1.960 OD 1.655 ID .375 Deep

The Valve Seat - 1.960 OD 1.655 ID .375 Deep from BRODIX is a precision exhaust valve seat engineered for high-performance cylinder head porting and engine rebuilds. This cast-iron component is essential for serious engine builders, mechanics, and performance enthusiasts who demand reliable sealing and durability under extreme combustion pressures. Whether you're restoring a classic muscle car, building a race engine, or performing a complete top-end overhaul, this valve seat provides the geometry necessary for optimal valve-to-seat contact and leak-free operation.

Manufactured from cast iron, this exhaust valve seat features a 1.960-inch outer diameter with a 1.655-inch inner diameter and 0.375-inch depth—dimensions that define its seating surface and interference fit within the cylinder head. The precise OD-to-ID ratio ensures proper concentricity and load distribution across the valve face, critical for preventing hot spots, carbon buildup, and valve recession over time. The 0.375-inch depth provides adequate material for multiple valve laps and seat grinding operations during initial setup and any future machine work, making it a durable choice for both street and competition engines.

This valve seat is ideal for mechanics and engine builders working with BRODIX cylinder heads or compatible small-block and big-block applications requiring exhaust valve seats of this specification. Installation requires precision boring to match the OD tolerance and careful seating to ensure full contact with the head counterbore. Proper installation and valve lapping are essential to achieve the sealing integrity that this component is designed to deliver. Each unit is sold individually, allowing you to replace worn or damaged seats as part of a complete cylinder head restoration.
