Description
Manley packages these Race Series intake valves for Ford 4.6L Modular V8 around the measurements that matter during cylinder-head setup, rather than treating every valve size as a separate shopping path. The parent listing is distinguished by 44.50mm Head / Part #11634-8, which should be cross-checked against the rest of the engine combination.
If the Ford 4.6L Modular V8 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.
