Don't know specifics but I do know there are head studs.

There is a set if SS on eBay for psd's. simple 3/8x16 stud about 1 1/2-2" should be fine. I used studs in mine. Had a bunch for big truck PTOs I've changed throughout the years

No specific kits available that I know of. Why are the thinking you need them. I agree they are a kind of dressy look but we have no way of making enough intake pressure to warrant the use. I feel if you want them just buy some 3/8x16 al thread material and cut them yourself. You probably wont be able to hand screw them into the heads and them install the manifold because of the angle.
can you provide a link to that? i cannot locate it.
as for why i want them, i believe studs are superior than bolts in all aspects, other than ease of assembly in a tight area. But I dont plan on doing exhaust gaskets anytime soon-especially not in the truck.

See if that works. Type in "7.3 diesel stud" it's the first one that pops up for me.

I guarantee you wont be able to install the manifold with studs already in the heads.
you would have to thread them in after the intake is on.
IMO it would be a (insert derogatory remark about my ex here) to even mess with.

We are talking about the EXHAUST manifold correct?? Because no way you'll be able to put the intake on with studs pre installed

True, but you did mention exhaust gaskets. I had exhaust manifold studs in mind from the first post.

I'm going to have to remember that one 
I suppose it's a moot point since the OP made it clear he was talking about exhaust studs...but, for anyone who wants to do intake manifold studs, there's no way you're putting them on before installing the manifold. I suppose it would be possible to get the manifold in place, then put studs in and nuts afterwards, but I'm not sure getting the stud out to remove the manifold would be possible even then...so, better to stick with bolts IMHO

DO NOT USE SS STUDS IN EXHAUST!! because at any point after it has been run, if needed to disassemble, breakage of the stud is very high and removeal of SS stud in head after breaking is very difficult. SS material is not a good exhaust bolt / stud material, it becomes very brittle and will not come out of heads. Use black carbon studs if you're going to use them. The factory had very good results with bolts or they would of used something else.
I guess thats why ford and engine builders use ss studs for their turbo engines?
Ss doesnt loosen up like carbon steel after repeated heat cycles
The factory used carbon bolts because they are cheaper than stainless studs.

there are different grades of SS. Just trying to give some insight, you use what you want, good luck.
One piece of advice. Slather everything in antisieze if you use stainless hardware on stainless hardware especially if there is any real torque involved. You will learn quickly if you ever have to remove them that pressure welding SUCKS!!! I have had to cut more than one vacuum system apart because the fasteners galled.
