Upgrade any of our cylinder heads to CHE Bronze Alloys Valve seat material. All standard finished cylinder head pricing comes with CHE Ductile Iron Valve Seats. Upgrading to CHE Bronze Alloys Valve Seats may be desirable in some applications. 

CHE’s proprietary Blended Bronze Alloys have been developed specifically with valve seats in mind. They have extraordinary wear resistance and greater thermal properties than all other bronze alloys tested.

These materials are excellent for extreme temperatures as seen in high horsepower applications. These work especially well in Nitrous Oxide and Turbo applications.
