Description
6.4L Ford Powerstroke Diesel Cylinder Head Set (Pair OF Heads 2) 2008-2010
Our popular heads start off with a 100% brand new heavy duty casting made to our exacting specifications. We have improved several key design flaws with the factory cylinder heads castings with higher nickel content and thicker deck surface, for a more rigid casting, and hardened alloy valve seat inserts. Our 6.4 heads have more material around the injector bores, and reinforced injector bolt holes to eliminate cracking in the injector bore, all finish machine work in house.
O-ring option: A receiver groove is machined into the deck surface of the heads and our USA made stainless wire is pressed into the groove – the wire protrudes from the groove applying extra pressure to all layers of the MLS gaskets – sealing combustion pressure in the cylinder. Our O-ringed heads work with any standard “off the shelf” head gaskets, and don’t require any special machining of the block – just prep the deck surface ensuring the block is clean, dry, and flat. valve guides are diamond honed to size leaving a smooth cross-hatch finish in the valve guide similar to the cylinder bore, which provides superior oiling and wear resistance. The heads come ready to install, with a 12-month replacement warranty against defects in quality and workmanship.
