Why ARP Studs?
As a new to the PSD Truck community, I too, was originally looking toward an older 7.3; but now the owner of a NEW to ME 2005, 6.0L I have been scowering the forums for WHY after 2004 Ford/International continued to use the Torque to Yield Bolts.
All I have been able to find is how great ARP studs are; and that they will solve most of the problems of the 6.0 (HGasket at least) and yet Ford continued to use the TTY bolts through the entire manufacturing cycle...
When I need a new HG then that will be the solution; by why was not this problem addressed from the MY 2005 on up?

Because the TTY bolts aren't always a problem at stock power levels and cylinder pressures, they work just fine for a lot of people. Warped and cracked heads, cracked injectors and busted EGR coolers probably lift as many heads as bad tuning jobs actually stretching the bolts.
Plus ARPs aren't magical, if you don't check the heads and block and reinstall warped parts, you can do repeat headgaskets even using studs. Plus studs won't stop a head from cracking.

The TTY bolts meet the clamping force requirements calculated by the engineers. Apparently, they didn't include the added pressure of coolant in the intake charge caused by a leaking EGR cooler, an over boost condition, aftermarket tuners, or any of the other issues that can raise cylinder pressure or corrosion from the coolant side.
Head studs don't really solve any problem, they simply serve to make the head gasket seal more tolerant to the higher than normal pressures they can see if any of the above issues are going on under the hood.

Thank texastech and Rusty...
The forums can be very confusing sometimes... especially when one reads about people with multiple HG and EGR cooler and Oil Cooler failures...
The other thing is that the marketing strategy of many aftermarket suppliers of things like EGR coolers, Oil coolers etc. use as one of their approaches that it is not a matter of IF but When.. these events will happen...
That's the same with all things mechanical...
