Kibblewhite Cast Iron Oversize Valve Guides for Harley Shovelhead

Kibblewhite cast iron oversize valve guides are precision-machined replacement engine valve guides for Harley-Davidson Shovelhead engines. They restore correct valve stem clearance and alignment in worn cylinder heads. Oversize guides are used when the original guide bores have worn or been machined larger during a rebuild.

Key Features:

• Made from a proprietary cast iron specification that Kibblewhite developed after chemically analyzing and testing many samples of cast iron
• Cast iron resists wear well and works with many valve stem materials
• Precision-machined and made in the USA
• Available in intake and exhaust versions and in a range of oversize steps, so you can match the guide to your head's bore condition
• Replaces worn OEM-style guides in Panhead and Shovelhead engines

Installation Note: Some guides need machining for seal installation, so check the specific part number's details before installing.

Kibblewhite is a well-regarded name in Harley-Davidson engine rebuilding. These valve guides give engine builders and restorers a durable, accurately sized replacement that supports long valve train life.
