Description
Manley packages these Titanium exhaust valves for Big Block General Motors - Dart Pro1 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 Part #11481-8, which should be cross-checked against the rest of the engine combination.
The correct Big Block General Motors - Dart Pro1 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.
