Nickel Bronze valve seats are the performance option for replacing factory seats when doing your cylinder head build. In high revving performance head builds, factory seats are prone to excessive wear resulting in premature valve failures. To combat these issues our valve seats are made from a specialized alloy, Using a proprietary bronze alloy results in faster heat dissipation where thermal conductivity is increased by 10% and extends valve life, seat erosion, and cylinder head component life.
