ARP Head Studs

[jordan572]

Does the 6.4 come with head studs or head bolts? After some short research it looks like the only way to go is with studs but I was just wondering what it looks like stock.

Studs and bolts are the same thing. Aftermarket studs are stronger than the stock ones.

The 6.4L stock comes with head bolts not studs.

Im pretty sure they arn't. A stud is threaded into the block then the head slides over that, finally a nut is tightened onto the other end of the stud.

Oh ok maybe I am wrong. Learn something new every day

yea studs are not the same as a bolt, a stud is threaded on both ends and you thread them into the block and then slide the head onto them and then put lock washers and nuts to hold them down. Factory uses Torque to yield bolts

Like stated above, your motor comes from the factory with head bolts. This is the case with any production diesel engine.

Head studs are recommended when you run the higher horsepower tunes available for the 6.4L Power Stroke. The factory head bolts on the 6.4L are pretty strong compared to the 6.0L, but there is a point where they will blow. It becomes more likely on the 250+ tunes, but a lot of people run the 300 HP level tunes for a long time with no issues.

ARP's or H-11 head studs will both work fine for your application. I personally prefer H-11 head studs due to the higher tensile strength, but both studs are proven.

Is the stud bolt swap a cab off job? Is it something a weekend mechanic can tackle or is it really tricky and has to have the cab off. I can take the cab off I have a lift. Just wondering . Thanks for the info.
