Description
This Manley Extreme Duty exhaust valve family is intended for Ford 4.6L builds where valve dimensions need to be matched deliberately to the cylinder head, seat work, and valvetrain geometry. 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.
The correct Ford 4.6L 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.
