The manifold fit my engine correctly. However, the ports were poorly shaped. I spent an hour port matching the manifold with the gasket via a grinding tool.

worked well. no more annoying ticking sound. 1 suggestion. Buy the stainless steel manifold bolts when replacing.

Perfect match to the over priced ford one,that's where the original ones.It sucks that the bolts brake off,then the EGR tube stripes off and you loose both. This does happen on all makes.

I recently purchased a 1998 Ford Expedition 4X4 with the 5.4 Triton engine to replace my older SUV that had seen better days. About a month after getting the Expedition, it developed the notorious exhaust gasket leak these vehicles are well known for. Now the gaskets on this vehicle had been replaced about five years earlier, however, they were now leaking again. Not really wanting to put more money into the truck, but the noise was getting noticeable and somewhat embarrassing.So after finding a mechanic willing to do the work, I decided to not only replaces the gaskets, but to replace the headers as well. This turned out to be a good decision. (The headers on the truck were rusted quite bad and were near the end of their life anyway) As a side note, I had seriously considered installing shorty style headers with the assumption they might improve my gas mileage. But after talking with numerous people who work on these trucks, they unanimously agreed that shorty headers on this particular vehicle would not be a good investment, and most likely the shorty headers would start leaking again in the near future. So factory style headers it was.I took these headers to the mechanic and he was very pleased with the appearance of these headers. It took him about 6 hours to replace both passenger and driver side headers along with replacing the studs. I helped speed up this procedure by spraying penetrating oil on all the studs for a week prior to installing the headers. Usually this job can be a royal pain and is not recommended to be taken on by the shade tree mechanic without the proper tools.The mechanic told me these headers were nearly twice as thick as the factory headers and were very well made. He also said I should not have to worry about these headers for at least ten years. While this is a good truck, and I am sure I will have long sold the truck by then.The only thing he didn't like were the gaskets that came with the headers. He felt they were a bit cheap and felt they would not hold up long term. He suggested getting the new style Ford gaskets which are made of metal. I told him to install the Ford gaskets as I didn't want to have to have this work done again. Those gaskets are about $120 alone. Not cheap, but considering everything, part of the expense and I shouldn't have to worry about this again.Since installing the headers, the truck is obviously much, much quieter and I seem to feel a bit of increase in power. Not sure of any mileage gain at this point.All in all I would highly recommend these headers as a factory style replacement to anyone facing this project with the 5.4 Triton Engine.
