Jag did not persue the quad cam heads because it moved the weight higher up which had an adverse effect on handling of the race car. They do make more outright power with the sacrifice of some low to midrange. Jaguar deemed it not worthwhile for the costs involved. There are still a couple of Jaguar built quad cams around I remember reading an article this year by a guy who bought one out of Germany.

There were several reasons: Flathead had better low down torque and midrange was perfectly good. Had they gone racing I guess they would have persevered with the 4 cam. In addition space was tight enough in the intended recipient, the XJ6 which was under way. To top it off the twin cam would have been more expensive to produce.

The quad cam was developed for the le Mans sports car racers not the XJS specifically the XJ13 and is a completely different beast than the AJ6 headed one in the post.
