Re: 01 Heads on a 96.
Same heads newer engine is all. The only difference between the 94.5-03 engines is that when they went to the superduty in the early 99 superduty they eliminated the hole in the valley for the mechanical fuel pump as they went electric and they changed the accessories around on the front of the engine. The heads are the same. Some internals such as the connecting rods were changed to powdered rods from forged rods.
