I'm assuming it's a 6.0 PowerStroke diesel, yeah? Those things are known for blown head gaskets... They're know for having plenty of issues. I was in a shop a few days ago and I asked an older guy working there if they saw many 6.0 diesels in there with issues, and he just started laughing...

Like I said, it's a common issue with those engines...
When a head gasket is blown, most people I've known of have replaced the head gasket and used aftermarket head studs.
The 6.0's are also well known for bad EGR coolers and clogged oil coolers.

Sure. Many people upgrade things like the EGR cooler and oil cooler to high flow units before they ever run into any issues with the stock ones. If you're going to be doing some work to it, you may want to look into these things.
Once you've done head gaskets, aftermarket head studs, aftermarket high flow EGR cooler, and an aftermarket high flow oil cooler, a 6.0 should last a long time without any trouble.

Also, the basic "tuners" tend to contribute to the HG problem.
The "custom" tuners are written to be safer for the HGs.
It's possible the EGR cooler has a hole, "possibly" caused by the
OIL cooler being partially clogged - restricting coolant to the EGR cooler.
This then allows coolant into your intake (via the EGR cooler) and this
fluid dramatically increases your cyclinder pressures causing your HG
to blow.
You SHOULD have an ODBII monitor/gauge (ie: scangauge2 or equiv) to
monitor your Engine Coolant and Engine Oil temps.
Good luck..

This is bad news, stock and blown HG at 93k miles. How old is your oil cooler, and do you know the oil cooler isn't plugged up? What are the temperatures spread between coolant and oil?

Here are SOME of the reasons for head gaskets leaking (JMHO):
1. Improper torquing of the head bolts from the factory
2. Heads and /or block not flat enough
3. Stretching of the head bolts due to excessive cylinder pressure or excessive heat
Some reasons for #3:
1. Turbo sticking and high boost values (also possibly from issues with bad MAP and EBP sensors)
2. Aftermarket power adders
3. Fuel or coolant hydrolocking a cylinder
4. Pushing engine too hard before fully warmed up.
5. Towing with a performance tune
6. Overheating the engine or the engine oil (plugged oil cooler, failed water pump, operating with improper coolant or coolant concentration, operating with excessively low coolant level, etc).

On the 2nd? high coolant pressure usually over 16 psi warm, using coolant, coolant in cylinder,...
