Description
Manley packages these Race Series exhaust valves for Ford 429 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, stem diameter, so the final SKU should be chosen from the dimensional requirements of the build.
For Ford 429, valve diameter changes can alter seat work and chamber/shrouding relationships, while alternate overall lengths can change installed height and rocker geometry.
