Description
This Manley Race Series exhaust valve family is intended for Chevrolet Small Block builds where valve dimensions need to be matched deliberately to the cylinder head, seat work, and valvetrain geometry. The parent listing is distinguished by 1.600"; Head / Part #11555-8, which should be cross-checked against the rest of the engine combination.
If the Chevrolet Small Block cylinder head has been ported, fitted with oversized seats, or changed from its original valvetrain layout, confirm the required valve measurements after machining rather than using a stock-size assumption.
