5.0L Mustang GEN 3 Valve Guides

GSC Power-Division manganese bronze valve guides are engineered for precision fit, durability, and reliable valve control in high-performance engine applications. Manufactured from high-quality manganese bronze, these guides offer excellent wear resistance, heat transfer, and long-term stability for both street and race use.

GSC offers standard replacement-style bronze valve guides as well as stopper-style valve guides designed to simplify installation and eliminate the risk of dropped valve guides. Stopper guides positively locate in the cylinder head, reducing install time while ensuring consistent guide height and secure retention.

All GSC stopper valve guides feature an integrated seal groove, allowing builders to remove factory hat-style seals and run a traditional metal-clad valve seal and spring seat when desired. This added flexibility makes GSC valve guides compatible with a wide range of valvetrain configurations and performance levels.
