Description
This Race Series exhaust 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.
The correct Ford 289 valve is the one that matches the finished head. Stem clearance, seat contact, installed height, spring package, and keeper location should all be checked during assembly.
