Description
Manley packages these Race Series exhaust valves for Volkswagen 1.7L Type IV around the measurements that matter during cylinder-head setup, rather than treating every valve size as a separate shopping path. The selectable configurations in this family are separated by head diameter, overall length, so the final SKU should be chosen from the dimensional requirements of the build.
If the Volkswagen 1.7L Type IV 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.
