The Edelbrock Victor Jr. LS3 cylinder head is a ground‑up performance design for LS3 engines that combines a 2.20" canted intake valve and unique port shaping to achieve nearly 400 cfm peak flow. Fully CNC‑machined intake ports, chambers and exhaust ports ensure consistency, and the head is capable of supporting very high output—manufacturer claims note capability of 650+ hp on an LS3 with stock rocker arms—making it suited for high‑power street or competition builds.
