no the mag set will not work with LA heads.. the cover water pump and and main accessory will, how ever the tensioner and pwr steer will not work on the older LA headed engines..the 91 LA engine in the dakota was by-itself and is what i am looking for.. I alos thought the mag set (93 3.9 v6) was a bolt on, till i got to the tensioner and pwr steering, and no way to bolt them up unless i fab some brackets.. I also just verified my find with Rick E-burger of mopar action as well.
