Pre-existing egr delete/headstuds?

I just bought a 2003 F350 srw with a 6.0 Powerstroke in it and I am aware of the common issues that these motors [I]can[I] bring along. I am fairly new to diesel trucks and I was wondering how I could identify if the truck already has an egr delete and/or headstuds... I understand that these items are burried under some layers but is there any way to tell if they are installed without digging through too many layers? The truck has 180k miles on it so I would have thought that if something was going to go wrong, it would have done so already.

Howdy and welcome to the ORG.

The EGR delete can be identified by looking under the intake manifold itself, in the engine valley.

Studs are a lot easier, look at the bolts holding the heads on. If it looks like a bolt, its the stock TTY bolt that stretches over time. If it looks like a stud (hex key imprinted on shaft) and a nut, then your truck is studded. This is not the cure all to keeping an eye on things, and depending on how the job was done the first time, it may need to be done again (when it fails, no reason to go back in there now)

Read the following thread on bullet-proofing and the core faults of the 6.0L:

Here are some pics.
Can you tell if your studs are done from the outside

Thanks for the quick replies and the info, it appears that the truck has an egr delete but it does not have studs.

With the delete in the truck, the coolant path that causes most of the HG failures doesn't exist. You should still monitor your ECT/EOT deltas for oil cooler replacements/rebuilds, but to prevent a rupture internal to the oil cooler vs a rupture of that EGR cooler which tears these motors apart.
