Designed with a 3.13" (8 cm) length and a 0.374" (0.9 cm) minimum finished inner diameter, these guide liners restore valve guides in cylinder head applications. They seat into a bored hole with a maximum inner dimension of 0.4055" (1 cm) to provide a stable foundation for valve operation. For optimal performance, the liners should be finished to the stated minimum diameter or larger during the final sizing process.
