Description
Manley packages these Severe Duty intake valves for Chevrolet LS7 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 2.205"; Head, which should be cross-checked against the rest of the engine combination.
The correct Chevrolet LS7 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.
