The GSC intake valve guide for Subaru EJ205, EJ207, EJ257 and EJ257B engines is a stopper-style manganese bronze replacement supplied as a single unit with a +.001in outer diameter oversize. It is intended as a direct-fit guide to maintain correct valve stem alignment and smooth movement in rebuilt heads. The stopper-style form aids consistent installation depth and retention in applications that use a physical stop.
