About This Product
This .010 inch oversize exhaust valve guide from Kibblewhite is the professional choice for 2017 to 2023 Milwaukee-Eight heads that need significant bore correction. Manufactured from high-quality manganese bronze, it offers the rapid heat transfer and lubricity needed for a reliable exhaust valvetrain. The .010 inch oversize on the outside diameter allows you to save cylinder heads that have worn or damaged guide bores by providing a secure, high-interference press fit. Manganese bronze is easier to work with than harder bearing bronzes, allowing for fast reaming and finishing with basic tools. It is a practical and effective solution for heavy-duty engine restoration, ensuring your M8 top end is back to factory-fresh tolerances.
Manufacturer part number: 20-21039M.
