Using high quality valve guides in your cylinder head is essential for longevity, reliability, and performance. Integrated Engineering valve guides are designed to directly replace OEM valve guides, featuring correct outside diameter measurements to provide the ideal press-fit into your cylinder head.
All IE valve guides are sold with an undersized inside diameter. This allows the engine builder to ream the guides after installation and set the stem-to-guide clearances exactly where they need to be, since different valve materials require different clearances. This feature eliminates any guesswork associated with replacing the guides. To make installation simple, we machine a small centering lip on the tip of each valve guide, which allows them to press into the head straight and consistently.
Integrated Engineering performance valve guides work as direct OEM replacements, while offering several unique features to improve performance and increase longevity. IE valve guides are manufactured in our CNC machine shop from a proprietary bronze alloy and feature ultra-high concentricity for exact valve placement. This ensures that the head of the valve sits in the exact center of the seat, removing any possibility of leaks. Our premium alloy improves wear resistance , reduces friction, and improves heat transfer. By increasing thermal conductivity by 10%, you can expect extended valve life and reduced wear on valvetrain components. To increase airflow through the intake and exhaust ports, we have designed our valve guides with aerodynamic tip that does not protrude into the airstream like the factory units. IE valve guides are designed to directly replace the factory guides and work well for all rebuilds, whether it be an OEM refresh or a complete race engine build!
