Description
Manley packages these Race Master exhaust valves for Ford Racing Cylinder Head 4.6L & 5.4L SOHC 36.0mm 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 36.0mm Head, which should be cross-checked against the rest of the engine combination.
For Ford Racing Cylinder Head 4.6L & 5.4L SOHC 36.0mm, valve diameter changes can alter seat work and chamber/shrouding relationships, while alternate overall lengths can change installed height and rocker geometry.
