The Fleece Performance Freedom Series HD Cylinder Head for the 6.0L PowerStroke - 18mm Dowel is built to OEM-or-better standards for diesel truck owners who want a no-compromise upgrade. Engineered, manufactured, and supported by Fleece - the diesel performance specialists.

Features
  • Brand-new, higher tensile strength casting
  • Race-proven formula with hardened, oversized press-in valve seats provides maximum durability and longevity
  • Fleece Performance exclusive single-piece O-ring design ensures complete combustion sealing vs. traditional stainless wire that must be seamed.
  • New valvetrain including Stainless Steel/Inconel alloy valves, springs, retainers, and keepers
  • No core charge or core to return.
  • Improved casting. This isn't your run of the mill, rinse and repeat OE casting. Engineered from the ground up with years of testing and development - our higher tensile strength alloy castings incorporate increased wall thickness and additional material where it counts, providing for a more durable and longer lasting cylinder head.
  • Extreme duty valve seats. Race proven and stronger than OEM - our American made valve seats provide for longevity and stability in the cylinder head. Produced from a tungsten alloy for increased hardness, these seats deliver a substantially higher wear resistance vs. a stock replacement seat.
  • Single piece O-ring. Our 6.0L cylinder head is the only cylinder head available with a single piece hoop style O-ring. Our single piece O-ring ensures complete sealing of combustion vs. traditional stainless wire that has a seam.
  • All 20mm dowel heads are configured for 2-bolt rocker box configurations.
  • Fleece Performance recommends the use of 6.4L pushrods (Ford Part No. 8C3Z-6565-B) when installing these cylinder heads. 6.4L pushrods are 0.050 inch shorter in length vs. a 6.0L pushrod and will accommodate the tolerance stack ups that can be encountered with a replacement cylinder head.
  • Head gasket not included. We recommend the use of Ford Part No.KZ3Z-6051-B.
  • Fits: 2003-2007 Ford F250/2003-2007 Ford F350/2003-2007 Ford F450/2003-2007 Ford F550

The warnings on the box say it's dangerous, the product page said it was safe.
Besides being much smaller than expected, this is from the box: + It's important to select the proper size & type of chew for your dog's age, weight & chewing strength. - "The Amazon page says it's 'Safe for All Dog Sizes.'" + Always supervise the use of all chews & toys - "The Amazon page says 'a safe alternative to edible chews when you can’t be home.'" + Product is not intended to be eaten or ingested. If you think your dog swallowed a piece, take the product away and contact your veterinarian. - "The Amazon page says it 'provides a safer alternative to real sticks. Safe non-toxic. A safe alternative to edible chews when you can’t be home." I've been disappointed by Amazon purchases before, but this is the first negative review I've written because this thing seems dangerous for dogs. I would report it to Amazon, but I can't figure out how.

It's not for aggressive chewers.
Flavor Name: Peanut Butter, Size: Large
The bone looks solid except for the brown strip wrapped around it. My dog chewed a piece of it off and tried to swallow them. I had to pull two strips of hard plastic out of his mouth. I threw the bone away.

Seemed to be flavorful
This toy started off strong. Could smell the chicken stock. by the next day the bone was destroyed. I am not going to say the product was weak, but my 60 lb. pit is a lot stronger, I guess. The material did not make a mess as far as I know, unless my dog just inhaled all of the tiny pieces

If you have a chewer - This is the bone for you!
I have purchased this bone three times and thought it was about time I wrote a review. My dog is a chewer - No matter how tough the toy claims to be, he rips it apart in minutes. And although he has a few hard bones, he prefers the toys he can damage. I received this bone as a gift and expected it to be another one that would fall into the pile of rarely touched bones. But this is the bone that he grabs almost every day. I honestly don't know what makes this bone different, but he loves it! It holds up to heavy duty chewing no matter how much he chews it. It holds its shape and (apparently) its flavor. Little bits do break off and it shows wear over time, but it is very long lasting. Added bonus - As a dog parent, I love that it has no smell and it never gets wet/sticky/gross.
