Valve Seat - Intake - 2.160 x 1.810 x .350

The DART Valve Seat – Intake – 2.160 x 1.810 x .350 is a precision-engineered powdered metal intake valve seat designed for serious engine builders and performance mechanics. This component serves as the sealing surface where the intake valve makes contact with the cylinder head, critical for establishing proper compression, fuel atomization, and combustion efficiency. Whether you're building a stroker, refreshing a high-mileage head, or upgrading to a performance camshaft package, a quality valve seat ensures consistent valve-to-seat contact and prevents compression loss that degrades power output and fuel economy.

Manufactured from powdered metal, this intake valve seat offers superior durability and thermal stability compared to cast alternatives, making it ideal for forced-induction applications, high-RPM builds, and engines running extended ignition timing. The 2.160-inch outer diameter, 1.810-inch inner diameter, and 0.350-inch depth are precision-specified to match OEM or performance cylinder head designs, ensuring proper bore fit and sealing geometry. Powdered metal construction provides excellent hardness and wear resistance while maintaining the dimensional consistency necessary for valve lapping, seat cutting, and final installation torque specifications. This material composition withstands thermal cycling and detonation events better than traditional cast iron seats, directly contributing to reliability in modified engines.

Professional machine shops and engine builders rely on DART valve seats when performing head reconditioning, bore work, or complete engine assembly on both street and race applications. Installation requires proper boring and seat machining tools to achieve the correct depth and concentricity; most shops will hone or lap the seat surface after pressing to guarantee optimal valve sealing. This particular specification fits common small-block and mid-displacement platforms; always verify your cylinder head's seat bore diameter and depth requirements before purchase to ensure compatibility with your specific rebuild project.
