I was talking to a mechanic at the dealership I work at. He's currently changing a head gasket on a truck and I told him the guy should have head studs. The technician then told me that it wouldn't matter, and that it's not a clamping issue but a heat issue. I'm looking for everyone's thoughts on this. I would assume everyone studs the head in order to prevent the head gasket failure and wouldn't recommend it if it didn't do anything. Thanks in advance.

well I guess it keeps him in work LOL
seen a few head gaskets blown and as far as i am concerned its because of not enough clamping force and can't contain the cylinder pressure
but I not so smart

Heat can be a part of the equation, especially if head temps went high enough to warp the head during a coolant system failure. However, most blown 6.7 gaskets are from excess cylinder pressure. I've seen head bolts that were stretched enough to allow the gasket to blow. Studs do allow for more clamping force and allow for less stretch, which does save a head gasket.

Right. Heat can be part of it, but say a smarter person was operating the vehicle and monitored temps, it shouldn't be.

Dealership mechanics.....
@Double R Diesel hits it on the heads. High pressures will always make/have heat and the two are very dangerious to your engine.
I asked an engineer before I retired to verified what I hoped was the answer.
(Sometimes a person likes being right once in their life)
Expansion/Contraction of the metals due to pressure AND heat over time weakends and strech the metal.
Original studs 'can be' retorqued, but are of a less quality of material, thus replaced over time.
Studs used to replace the originals are made of a higher quality material and have to ability of being retorqued several times by maintaining specific length.
So due to the quality of metals, the original studs are more or less designed for eventual replacement.

I was told not to do the studs, my local shop by my house told me if i want a guaranteed fix i should have my heads fire ringed.Originally Posted by Double R Diesel
That's what you think buster.
That is 100% correct. That's one of the reasons why there was so much trouble with aluminum heads on the gassers.
These engines are tested with continuous running. Hour after hour, mile after mile. Have you ever noticed a young car with lots of miles has very little trouble? They're not tested in an environment like mine. A light every 1/4 mile and a hundred Honda's under foot.
It's interesting. I looked at the service intervals and items on the 5.9. Not one mention of the head studs. High boosts and showing off usually is the culprit for a head gasket. Cummins has it down pretty good. In poking around over the years, Ram's are the biggest gasket gobblers. It's all those tuners and add ons.
My truck is running so clean, my boost is low. I cruise on the flats at 3 PSI on the flats.

@Polaraco hit the main problem in one sentence ..... "It's all those tuners and add ons."
It seems to me that when these are added, the younger person in us comes out and we deside that our 9,000 truck can be a 'vette and our foot can't stay off the skinny pedal and eventually our head gaskets or other parts tell us to slow down.

I see some of us are still large children. LOL I have a Smarty like you. I can't use my performance because I'll run over someone. But I did go to North Carolina last week and got 24.7 MPG though@Polaraco hit the main problem in one sentence ..... "It's all those tuners and add ons."
