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.
