KIBBLEWHITE Valve Guide - Exhaust - +0.010" 30-33639

Worn or damaged valve guides compromise cylinder head integrity and allow oil to seep into combustion chambers, reducing performance and increasing emissions. KIBBLEWHITE's +0.010" exhaust valve guides are precision-engineered to restore proper valve seat geometry and clearance, ensuring reliable sealing and consistent power delivery across your engine's operating range. Built from Ampco-45 bronze, these guides deliver superior heat dissipation and wear resistance—critical for high-RPM applications where thermal stress is constant.
