The GSC intake valve guide for 2008 and later Dodge Viper engines is a manganese bronze replacement offered as a single unit with a +.001in oversize outer diameter. It serves as a direct-fit guide to maintain proper valve stem alignment and consistent operation in rebuilt heads. The modest oversize helps achieve an accurate fit where the original guide bore has been fitted or lightly machined.
