Description
This Race Series intake valve listing is organized specifically for Ford 289, with the available dimensions presented as selectable configurations for easier cylinder-head planning. The selectable configurations in this family are separated by head diameter, overall length, stem diameter, so the final SKU should be chosen from the dimensional requirements of the build.
If the Ford 289 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.
