Im not into the bling factor but ARP makes SS 10mm X1.25 x55mm or 48mm long studs that would look great

Just thought some 1 might be interested in these You should never use a bolt in a head it will work but your going to have striping problem if u remove them very many times

I don't see why these cant be used correct me if I'm wrong, these have 180,000psi tensile strength can be torque to 57lbs and have 9,970lbs preload that is way more than a 220,000psi 8mm stud can handle

But the OEM studs are not the weak point, it's the aluminum cylinder that the studs are screwed into that is the point of failure. Plus, you only at most need to torque the nuts down to 21 Lb-ft.

Striping problem with bolts? No.

You can even get them in blue

You are clueless. You know how many engines use head bolts instead of studs?
You will not strip out a bolt if you use the correct wrench.

maybe,No how many Where not talking about the head of the bolt The aluminum is weak in the cylinder A bolt wouldnt be a good ideal in a quadracer cylinder BC The aluminum is weak this is a quadracer site

What difference is there with a stud and nut torqued down to 25psi and a bolt torqued to 25psi?
There is none.

Im not gonna start and am not gonna fight but a stud is stronger than a bolt. i used to use bolts for my cylinder and it really blows way nicer to have studs. I guess another thing to me is why not iuse the100$ you will spend and buy something that will actually improve performance..

The problem is the integrity of the threads in the cylinder. A stud will be threaded down till it bottoms on the shoulder of the stud locking it in, then the nut being torqued onto a secure stud. A bolt its gonna be torqued with rotation of the bolt threads pulling on and putting a lot of stress on weak Aluminum threads.

Threads / psi (I think this is the correct term) is the difference. For example, lets say that we can screw a stud in to max depth (where it bottoms out) which is 20 threads. Until there is an object such as a cylinder head to be torqued down, there will be 20 threads engaged at 0 psi. Once torqued to spec, all 20 threads will share the load.

To screw a bolt in, even the appropriate length one, You will start to exert tension on it once the head of the bolt makes initial contact with the top of the object to be torqued. This means that at initial contact, you may only have 15-16 threads engaged. At 50% torque load, you may only have 17-18 threads engaged. That leaves 2-3 threads still unused while the remainder of the torque is being applied. In theory, this is why the threads become stripped more easily when trying to torque a bolt as opposed to a nut on a stud.

A stud will provide more consistent torque load on the head and a bolt will stretch way before a stud will of the same grade. But if u wanna use bolt go for it. This to me falls into the catagory of copper gaskets, 10mm head studs, copper silicone, and all the other things ive heard ppl talk about pertaining to heads over the years. If thats how u want to assemble your engine i say go for it. Ill stick with my stock studs and o-ringed head.
