The head studs on the 6.0L Power Stroke are susceptible to failures due to a number of reasons. A leaking EGR Cooler will contaminate the cylinders with coolant, causing a hydraulic effect that will stretch the head studs and cause the head gaskets to fail. Also, the head studs pass through an aluminum carrier and a cast-iron head. The aluminum and the cast iron expand and contract at different rates which can weaken the factory grade head studs and hamper their ability to do their job. Additionally, the aluminum carrier does not allow sufficient clamping force with the factory head studs to withstand the extreme pressures that the 6.0L engine produces.
In addition to upgrading your Engine Oil Cooler and installing an EGR Cooler Delete Kit, we recommend installing a set of ARP head studs and Black Diamond head gaskets that will not only hold up to the extreme pressures that the 6.0L engine demands, but will also withstand aftermarket turbocharger boost pressures beyond anything that your factory replacement heads studs and head gaskets can offer.
