Description

Int Std C630 Vlv Guide Yam

  • California Prop 65 Warning: Cancer and Reproductive Harm - https://www.p65warnings.ca.gov/
  • Type: Valve Guide
The Kibblewhite C630 Racing Bronze Valve Guide is designed for high-performance off-road applications. Made from premium C630 nickel bronze, it features 80% copper for excellent heat conductivity, 5% nickel for superior wear resistance, and 10% aluminum for compatibility with aluminum cylinder heads. The guide profile is optimized to minimize airflow obstruction while maintaining critical cross-sectional thickness in high-temperature areas, promoting both durability and performance. In many cases, simply installing these guides enhances airflow without additional modifications. A flange design ensures proper protrusion for correct seal-to-retainer clearance with aggressive cam profiles, eliminating the need for repeated measurements during installation. Where a flange is not suitable, a reduced diameter above the purchase area indicates the correct protrusion. Precision manufacturing ensures tight concentricity tolerances, maintaining optimal alignment between the valve seat and guide, reducing material removal during valve jobs, and ensuring consistent chamber volumes. A smooth radius at the transition from the nose profile to the main body prevents galling during installation. The C630 Racing Bronze material is mill-certified, ensuring consistent quality with superior resistance to galling, allowing for tighter clearances, improved valve-to-seat sealing, and enhanced oil control. Sold in sets of two unless otherwise noted.
