Description
Manley packages these Titanium exhaust valves for Chevrolet Big Block - Brodix SR20 - Dart 20 Degree 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 #12213B-8, which should be cross-checked against the rest of the engine combination.
The correct Chevrolet Big Block - Brodix SR20 - Dart 20 Degree 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.
