Kibblewhite Precision Intake Valve Guide +0.002in

• Type: Valve Guide

The Kibblewhite Precision Intake Valve Guide (+0.002") is designed to optimize airflow while maintaining durability in high-temperature areas. The guide's shape enhances performance, and its precise tolerances ensure minimal material removal during valve jobs, leading to consistent chamber volumes and better valve-to-seat sealing. Manufactured from C630 Racing Bronze, it features 80% copper for excellent heat conductivity, 5% nickel for superior wear resistance, and 10% aluminum for compatibility with aluminum cylinder heads. This material is highly resistant to galling, allowing for tighter clearances and improved oil control. Alternatively, the Manganese Bronze variant offers an economical option, maintaining KPMI's exacting tolerances but with reduced hardness and wear resistance. These guides are easier to ream and finish using standard tools. A flange or diameter transition ensures proper protrusion during installation, eliminating the need for repeated measurements. The kit includes two valve guides.
