Description
This Manley Race Master exhaust valve family is intended for 2011+ Chrysler/Dodge 6.4L Hemi with Triple Groove (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 Set of 8, which should be cross-checked against the rest of the engine combination.
If the 2011+ Chrysler/Dodge 6.4L Hemi with Triple Groove (1.654) 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.

Selection & Fitment Notes
Valve fitment should be verified from the cylinder head itself; check the required head size, stem size, overall length, seat work, and valvetrain geometry rather than relying on engine name alone.
Professional engine assembly and measurement are recommended. Product specifications should be confirmed against the selected Manley part number and the requirements of the exact engine build.
