Remanufactured? No - poorly washed and painted junk yard Heads
I ordered both left and right heads for my 2004 F150 5.4L 3V Triton Engine.
They were well packaged in clam shell type reusable hard plastic case. Upon initial opening, a cursory glance they looked OK. But that weekend when I put them on the bench to inspect them is when I quickly and without hesitation, decided to return them promptly to my local Auto Zone store.
I have attached photos and they should be self explanatory.
I realize these are "re-manufactured", but that doesn't mean lack of attention or poor quality control and in all likelihood they may have ran fine, but I'll let someone else gamble on that.
I received 2 mismatched heads, meaning from 2 manufacturers. One was a Ford OEM head and one was a aftermarket head made by company I've never heard of. This means I would be running 2 different branded / mismatched CAMs, etc which was evident by the part #'s.
The Ford OEM head still had gasket residue on the block mating surface, and the head was spray painted gray and there was paint over spray all over the valve springs and valve stems. All of the valves, springs, followers, lash adjusters and CAM were re-used. Normally, this isn't an issue. However, it's a big NO-NO to re-use these components not in their original location from which they came from because of established wear patterns. I was able to identify the wear patterns and they didn't match (between the follower and lash adjust tappet, for example). The gasket surfaces for the intake, exhaust and valve cover were painted. While some say this is OK for gaskets, others say no it's not. Personally, I think it's to cover imperfections and make it look pretty and new. The gasket surface for the valve cover was badly pitted, as aluminum can do when exposed to the elements. It was pitted and rough even where the rubber gasket would go. Lastly, and the biggest deal for me is that on these Triton engine heads, there are no cam bearings which means the CAM rides on oil inside the journals. When there is a low oil issue, the CAM presses against the journal caps and steel on aluminum doesn't end well. I took off the journals on this head and found damage. In doing so I also found the bolts were still grimy and gritty and were never cleaned. In fact they spray paint the caps of the bolts blue, and this paint just covered the grit hiding out on the bolt caps.
The after market head looked like it had never been used. All gasket surfaces were shiny metal, no paint. It appeared there was an issue that was fixed via welding of some sort and re-ground down. Then I noticed a crack going across a bolt hole on the valve cover surface. Then again notice all the followers and lash adjusters were used, and not even cleaned. There was still caked on grease/grime on the followers.
Overall, no thanks. Over $1,000 for 2 re-manufactured heads and I'm not sure what value I'm getting out of them. I decided to rebuild the original heads that were on my truck by buying all new OEM parts for them and getting them cleaned and inspected. All this for about the same price, but more time. If Surefire's quality control let these heads go out, there was no way I was going to play the exchange game.
The Auto Zone parts manager was sympathetic and viewed my photos and looked at the heads. All he could do was shake his head in disbelief and apologized. I got a full refund.
