Head stud question

[Frankf250]

Hi all, got a question. Someone i work with has an 03 6.0 and decided to put in head studs without taking the heads off. How bad of an idea is that? Just curious what you all think.. He basically took each bolt out individually and put a stud in and torqued it down. One at a time.. What's the verdict here? He drove abou 1200 miles so far and all seems ok.

It's not a problem, it's just not a guarantee......not too many post with people who say it works well or not.

I'm getting ready to do exactly what he did. It will be done by Sunday. I'll be sure to let everyone know how the truck does as the miles rack up.

I will post the end methods since I'm sure things will change. That said, the plan is to do it according to ARPs recommended order for torquing them down. I am going to start out taking them to 140 ft lbs and once they are all in I will go back through and torque them in the same order to the full 210 ft lbs.

If everything is tight, quite a few people have done it without issue.

IMO it is crazy to do it if your head gaskets have already been leaking.

Question is - how do you know for sure everything is tight?

I see no problem with doing one at a time if the HG are not leaking. But, are studs really necessary if the TTY bolts are holding? I don't think so in a stock or near stock configuration.

I think the the HG's are popping because of hyd locking caused by EGR failure or an engine over temp which will stretch head bolts on any engine. Proving that this has never happened on your engine is the key.

I'm not planning on doing studs unless a problem shows up that requires pulling the heads.

Subscribed and a BUMP for those who done this can chime in, I am thinking of doing the same thing.

Mine where done one at a time. Going on 2000 miles with innovative tunes ran hard. Motors happy transmission not so much. Haha

What sequence? One out, torqued 100%, then to the next?
