UPGRADE YOUR CYLINDER HEAD WITH IE VALVE GUIDES

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.

Valve guides are small cylindrical bushings that press into a cylinder head, giving valves a place to reciprocate with minimal friction and wear. They facilitate valve movement and keep them perfectly centered on the valve seats. Lastly, they allow heat to transfer from the combustion chamber into the cylinder head, which is then cooled by engine coolant.

When it comes time to rebuild your cylinder head, it's very likely that you will find the OEM valve guides worn beyond wear limits. As mileage begins to add up, the inside diameter of your valve guides will wear, causing e
