The Fleece Performance Freedom Series HD Cylinder Head for the 6.0L PowerStroke - 20mm 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.

Reasonable substitute for real copper wire
Color: 40FT Wire+40FT Cable Sleeve
Nice cable set. This will be very handy when I install my inverter in my camper van. While I don't really like the idea of copper clad aluminum (it's cheaper than 100% copper) as long as it doesn't wiggle around much, it'll work just fine. The crimp connectors are great- not as heavy as I would like but they will do the job. Overall, an OK thing to buy

Nice wiring kit with CCA wire.
Color: 40FT Wire+40FT Cable Sleeve, Color: 40FT Wire+40FT Cable Sleeve
This is a nice kit with a lot everything you need to wire up your project. This is CCA wire, so make sure you use it in the proper way. It will not take as much amperage over as long of distance as OFC wire will. The wire itself is good quality. It is true 0AWG and quite flexible making it easy to route through your project. The lugs crimp easily and hold well. The split look wire protector it nice quality and works well. The tool supplied to insert wires into the split loom is amazing. I have never used a toll like that and it works so slick.

Don’t use for automotive
Color: 40FT Wire+40FT Cable Sleeve
Don’t get me wrong it’s not a horrible product but these wires have an extreme amount of resistance to them, and once they get hot they drop voltage drastically. It was nice it came with a bunch of eyelets and made it easy to assemble but unfortunately once they were over 100F temp (live in Florida so cars get way hotter than that on the inside) the voltage would go from a normal 12.5-13.5v all the way down to 8v. Partially my fault I did not notice they were CCA wire instead description, would not recommend for automotive use.
