When you are performing high-quality head work, these Kibblewhite cast iron valve seats offer the reliability you need. Manufactured in the U.S.A., these seats are compatible with leaded and unleaded fuels, including modern ethanol and methanol blends. This seat is designed with a 44.00mm outside diameter, a 34.00mm inside diameter, and an 11.00mm height. Suitable for use on either the intake or exhaust side, the cast iron material provides superior thermal properties and resists the micro-welding that can occur in high-stress environments.
