This is a question often asked. Why should I install head studs when replacing the head gasket on my truck? Why can’t I just use the factory style head bolt?
In a diesel application there is a very high cylinder pressure which is very hard on head gaskets. The factory style Head Bolt is a torque to yield bolt. This means that you torque the bolt to a specific torque and then in most cases do a 90 degree rotation on the bolt which will put it in its optimum stretch point. This will then create the maximum clamping force of that fastener.
Shop for Head Studs
We have found, over the years of working on diesel trucks, that when you add horsepower with things like chips, programmers, injectors, and larger (or multiple) turbochargers you are at a higher risk of creating that high cylinder pressure lower in the RPM range resulting in a blown head gasket.
The design behind a head stud is to have a fastener that does not stretch. This is done by using a high tensile strength alloy and a stud rather than a bolt. The stud allows for a fine thread nut on the top which will result in a more precise torque of the head.
We highly recommend that whenever you are looking at replacing your head gaskets that you add the insurance of installing a fastener that will not stretch and put you back in the same position of replacing another head gasket.
At East Coast Diesel we sell a complete line of the ARP Fasteners. This includes Head Stud kits, Main Stud Kits as well as Rod bolts and many other applications. Let’s face it, who wants to take power away from their truck in order to keep it from blowing a head gasket, hence the reason to install head studs.

We all know that the Ford 6.0L Ford Powerstroke Diesel has had all kinds of issues; Blown Head Gaskets, Plugged Oil Coolers, Fried FICM’s, Cracked EGR Coolers, and the list goes on and on. There are all kinds of theories out there as to why these injectors fail and what can be done to make them last longer. There are additives, special oils, and so on. If you have tried all these magic formulas and your injectors are just too far gone to save them, you’ve likely decided you are going to go ahead and buy injectors for your truck. Now the question is which brand of injectors do you buy? You research, and there again you have all kinds of options, suggestions and theories.
Shop 6.0L Injectors
We’d like to help you address the issue of having to replace injectors in your 6.0L. At East Coast Diesel we believe that the best injector you can purchase for your 6.0L is the Genuine Motorcraft Injector. This injector is the only injector that has a New Spool Valve. The spool valve is in the top of the injector and is the number one reason for your truck to have a hard starting issue and a rough idle after startup. This spool valve actuates side to side at a very high rate of speed with a very tight tolerance allowing the high pressure oil to move through the injector causing the injector to fire. With lack of service, such as a good quality oil change on regular basis, these spool valves will wear, causing them to stick and hence the term injector stickage.
Aftermarket rebuilders will reman the 6.0L injector for as low a cost as possible. This will often result in the spool valves being reconditioned and or tested and reused. With the spool valve being the number one reason for 6.0L injector failure, it would be a mistake to purchase an injector that has anything less than the a brand new spool valve!
