Description
This Manley Race Master exhaust valve family is intended for Chrysler Hemi 6.4L (1.654) builds where valve dimensions need to be matched deliberately to the cylinder head, seat work, and valvetrain geometry. The parent listing is distinguished by Part #12331B-1, which should be cross-checked against the rest of the engine combination.
The correct Chrysler Hemi 6.4L (1.654) 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.
