A correlated set of golf club heads comprises a first and second golf club head. Each club head has a striking face, a rear surface, a top portion, a sole portion, a toe portion, a heel portion, and a loft. The striking face has a first plurality of scorelines defining a scoreline heel-ward extent and a scoreline toe-ward extent. The plurality of scorelines comprises a scoreline length LS1 being the lateral distance between the heel-ward extent and the toe-ward extent. The loft of the second golf club head is greater than that of the first golf club head. The scoreline length LS2 of the second golf club head differs from that of the first scoreline length LS1.
