The GSC intake valve guide for Ford Mustang 4.6L SOHC 2-valve engines is a manganese bronze stopper-style guide supplied individually with a +.003in outer diameter oversize. It replaces the factory guide to maintain valve stem positioning and dependable operation in serviced heads. The stopper-style form factor matches applications that use a physical stop feature to control guide insertion depth.
