Biggies are:
Head studs.
Head Gaskets.
EGE delete.
Oil cooler (as mentioned above)
Blue spring fuel pressure upgrade
ELC coolant

Some will throw in bigger injectors, different turbos, upgrade some other internals and I’m sure several things I’m forgetting


Almost got it, Bulletproof was a term coined by Bulletproof Diesel in AZ as mentioned.

It does include head studs (might as well replace gaskets at this time but not required) and oil cooler replacement. However, it is an EGR replacement cooler not delete as well as a FICIM upgrade and new waterpump to complete a Bulletproof engine.

Anything else isn't correcting the major failures in the 6.0L engine.
