Ferrea Chevrolet LS1 .3138in .502 OD 2.000 Length .500 ID Exhaust & Intake Valve Guide - Set of 8

Ferrea is known for making high-performance valvetrain components, and these valve guides for Chevrolet LS1 engines are no exception. If you're rebuilding or upgrading your LS1's cylinder heads, getting the valve guides right is crucial for proper valve sealing and smooth operation. This set includes eight guides, enough for a complete engine.

These guides are designed with specific dimensions: a .3138-inch inner diameter, a .502-inch outer diameter, and a 2.000-inch length, with a .500-inch ID. These precise measurements ensure a snug fit within the cylinder head and proper clearance for the valve stem, which is important for preventing leaks and ensuring the valve seats correctly every time. Getting the valve guides installed properly is key to the overall performance and longevity of your engine build.
