I'm buying SCT X3 and would like to do my ARP stud changeover myself. I do not have any head gasket problems and would prefer not changing them since they are not leaking. I read one reply to an ARP and Head gasket job posting that if you do not have a leaking head gasket, you can just replace the head bolts one at a time with the ARP bolts. Assuming that everything is torqued up per ARP instructions does this sound correct? If it can be done this way what are the obstacles and any time saving tricks that I need to be aware of?

 

you might be able to but i would not recomend it, once your in there and all that is involve with doing the headstuds on a 6.0 you might as well do it right.

 

Ive read about guys doing the studs without removing the engine or lifting the cab.

 

Yeah maybe you can but i would just change the gaskets too cause your gonna be one pissed off puppy if you do all that work then your headgaskets start leaking a little bit down the road

 

I'm not even sure what the stock tunes built into the SCT X3 add to the H.P. Do they add a serious amount of power and should I be concerned about the stock 2006 head bolts at these power levels? I'm not drag racing my truck. It's primarily going to be used to haul about 8,000# of toys on top and behind.

 

Im not 100% sure but i think the 6.0 headgaskets are a crapshoot, some will handle more then others, yours being an 06 i think they started getting some of the problems figured out by the later years so you might be ok

 

I had an 04 6.0 and used a custom tuned SCT Xcal2 and never had any issues other than not so good fuel mileage. Let me know if you need a Xcal2 I can can make you a great deal on one as well as some great service after the sale.

What's the difference between the x3 and that? Just memory capacity?
What is loaded into it and how many vehicle changes are left in it?

 

Anther reply to my question on another site indicates that I may be able to raise the cab about 10" and getter done but involves disconnecting at least the steering and coolant hoses. Any other must remove items I'm missing?
I'm sure removing cab bolts and lifting and cribbing with several floor jacks is the easiest part of doing a slight lift.

 

There's a number of guys over at TheDieselGarage that have done it one bolt at a time and have no problems at all, did it without removing the cab or anything either. I think one of the guys did a bit of a write-up that I can try to find if you want.

If you get the SCT and get custom tunes written for your truck, that will greatly reduce your chance of having any problems... Heard of lots of folks runnin them for a very long time without issues. A lot of it is in how you drive the truck and take care of/maintain it. My tunes were written by Innovative Diesel and they are awesome tunes, put down lots of power, and are pretty safe. They told me that the levels they tuned it to are the maximun safe without studs, but I could add more if I studded the truck and some other things too... My race tune is supposed to be 430 at the wheels.

An approach that I think is good and I reccomend, is to start putting aside a little bit of money each month to save up for when the HG's do decide to go. At that time I am going to have a bunch of stuff done since the cab will be off.


I do realize I don't have much of a post count, but that doesn't mean I don't know anything about these trucks, I have been a member on another site for a few years and do most of my own work... Just didn't want anybody to say "he's a newbie, he don't know anything."

X3 is newer and a bit faster. You can't buy an X2 new anymore
