About this product
About this product
The Kibblewhite Fat Stem Valve is engineered to address a common issue in some Twin Cam heads that utilize 7.0mm valves: cracking in the port end of the valve guide boss. This valve provides a reliable solution for restoring optimal valve stem to valve guide clearance.
Description
This Kibblewhite valve features a .005" oversize stem, carefully designed to re-establish the correct valve stem to valve guide clearance in heads that have experienced cracking. Proper installation requires reaming or honing the valve guides to achieve the correct clearance, followed by a valve job to ensure a proper seal. This ensures optimal engine performance and longevity. The oversize portion of the valve stem is strategically designed to not extend into the keeper groove area, allowing for the continued use of OEM valve keepers. Enhance your engine's reliability with Kibblewhite's precision-engineered valve solution, specifically designed for Twin Cam applications requiring a valve with a 0.2805" stem diameter and 1.575" head diameter.
