The Valve Spring Locators 1.410 OD .567 ID from Manley are essential precision components for high-performance engine builds where cylinder head assembly integrity directly impacts reliability and power output. These locators are designed for builders and mechanics who demand OEM-quality parts that maintain consistent valve spring seating geometry, preventing spring migration and ensuring predictable spring rates throughout the RPM band.
Manley's valve spring locators feature precision-machined dimensions with a 1.410-inch outer diameter and .567-inch inner diameter that mate directly with your valve spring assembly and cylinder head pocket. The tight tolerances maintain exact spring pre-load geometry, preventing valvetrain harmonics issues that emerge when springs shift under high-load conditions. Unlike budget alternatives, these locators are designed to withstand sustained high-RPM operation without compressing or deforming.
Professional engine builders and dedicated enthusiasts rely on these valve spring locators during complete engine builds, ensuring compatibility with both ported and stock cylinder head configurations. Their reliable performance is crucial for any serious engine modification project, whether building a naturally aspirated stroker or a forced induction platform.
