Description
Engine builders working with Chevrolet LT1 6.2L can use this Race Master exhaust valve family to choose the required valve dimensions while staying within the correct Manley application group. The parent listing is distinguished by 1.590"; Head / Part #12345-1, which should be cross-checked against the rest of the engine combination.
The correct Chevrolet LT1 6.2L valve is the one that matches the finished head. Stem clearance, seat contact, installed height, spring package, and keeper location should all be checked during assembly.
