6.0 Powerstroke Head Gaskets. Ford vs Mahle Black Diamond

There has been quite a bit of debate about 6.0 Powerstroke head gaskets. “Which is the best?”

Black Victor Reinz head gasket with VR stamp and part number. Blue Ford OEM head gasket with VR stamp and Ford part number X’d out. We received 6.0 Powerstroke X’d out gasket in a genuine Ford Parts box from a dealership.

The only difference between Ford 6.0 Powerstroke OEM head gaskets and Mahle/Victor Reinz Black Diamond head gaskets is the color of the adhesive. We have actually received OEM Ford head gaskets, delivered to our shop from a local dealership that had the Victor Reinz logo stamped into them along with the Ford part number.

Don’t believe it? Here is an interesting post by Chistine “Pinky” Ruggles at Bullet Proof Diesel about a comparison between the two head gaskets for the 6.0L. http://www.powerstroke.org/forum/general-6-0l-discussion/971506-6-0l-head-gasket-comparison.html#post11811546

In summary Pinky wrote, “we noticed a few things:”

“Between 2012 and 2015, Victor Reinz has notably changed their gasket manufacturing. Two main changes are observed, the first being the measured thicknesses of each layer of the gasket, especially the 4th layer fire ring. This contributes to the difference in the overall thickness of the assembled head gasket as well. The second change is the absence of a completely sealant covered gasket layer; present in 2012, and now absent in 2015. These differences, when compared to the Black Diamond and River City Diesel Platinum gaskets, gives credibility to the idea that these (in addition to OEM gaskets) are all manufactured in the same place.

The Black Diamond, River City Diesel, and OEM gaskets all contained the stamped part number 6237557 on the second layer.

Asheville Engine offers your choice of the Mahle Black Diamond head gaskets which are included in the engine prices posted on our web site or for an additional charge, we offer Ford OEM gaskets as an upgrade.

    Do you have a name and number of a person in Indianapolis Indiana who installs your engines?

      Bill, Thanks for contacting us. I emailed a list of 7 shops in the Indianapolis area who install our engines as well as two that we would recommend that you stay away from.

    I’d like to know if you have recommended 6.0 shops you’ve sent engines to in the Denver, CO area.

    What kind of price should I expect to install it? I would be doing the typical EGR & Oil coolers at the same time.

      We’ve got a lot of diesel shops in and around Denver, CO who install our engines. I just emailed a list of 14 shops within 30 minutes of downtown Denver so you can decide who to call. Installation prices vary based on how many other parts you replace under your hood and different labor rates around the country but you can expect that your quote should be for about 28 hours of labor to replace a long block.
