Questions About Future Proactive Steps On A 6.7L With 257?

**Smoked** · 2 Weeks Ago

I have a new to me, 08, with 256k on the truck.

I am very familiar with the truck's history; it was documented and well-maintained before I took ownership of it.

Mods:

Weight loss with EFI Live
Upgraded Intercooler, Radiator, and, I believe, a 64mm turbo.
Injectors

It runs flawlessly. It sounds better than my 18 does, and I am having ZERO issues with it.

That said, with that kind of mileage, I am wondering about the future of the engine.

It has factory head bolts. I believe the head gasket and injectors are all in stock as well.

The question is, if I want to head stud this thing and replace rods and valve springs as well, should I pull the head and replace the gasket or just throw caution to the wind and do a one-at-a-time head stud install as well as replace injectors, springs, and rods?

Longevity is the goal.

The aftermarket turbo is pretty nice; I am not complaining about it, but I think I want life expectancy over power.

With the miles associated with the truck, "which isn't a lot," I would remove the head and resurface it just for the piece of mind that you only have to do this once.

Studs are really important.

Since it has EFI live, I assume studs would have been installed already if you were running at higher power levels.

Is it the fleece cheetah VGT turbo that's on it now?
