Just picked up a Ford F-350 and wanted to know how to tell if it’s been bulletproofed or not.

 

You've neglected some vital information. I want to say the PowerStroke tag is indicative of the 6.0, but I am not 100% The F-250 tag could be either the 7.3 or 6.0.

 

Sorry, that would be The 6.0

 

If you are not familiar, "Bullet Proofing" is the removal of the emissions controls equipment that have become notorious for failing and/or causing other problems and failures. There are a number of other failure prone items on earlier 6.0's but they should have already been covered under recalls, with the exception of the head bolts. If you keep the truck stock you shouldn't have any issues, but if you plan to build power ARP head studs are usually highly recommended.

As far as bullet proofing, search some youtube videos of bullet proofing a 6.0 and you will find videos of where people are deleting their Exhaust Gas Recirculator (EGR). Then go and look and see if you have an EGR or not.
