In the process of installing my head studs... I noticed that the head stud on the intake side protrudes through the ARP provided nut and washer more than the exhaust side. Just eyeing it, it's about 1/4" on the exhaust and almost 1/2" on the intake. Is that normal? It is torqued down to 85 ft/lbs. Just not sure.

Out of all the people who have head studs, no one knows?

So after hand tightening the stud, I put the washer on and then the open ended nut. When I start to torque the nut, the stud goes in further. BUT when it reaches 85 ft lbs the stud goes through the open ended nut more than the other side. Attached is my quick photoshop drawing.

The top piece is the stud, the bottom piece is the nut. I don't know if the 9 is different but should I take that stud out, retighten it by hand, then try to re-torque it?

Make sure all the holes are clean and dry before inserting the studs.
You don't want the hole to be filled with oil or debris when torqueing it down.

I did that. I got a bunch of equipment cotton swabs on 6 inch sticks. Put em in there until there was little to no oil left on it. I will just take it out, try to clean it again, put it back in.

Here are pics of the difference that I am talking about. I took the stud out, cleaned the threads on the stud and in the head/block. My swab came out light gray with little to no oil on it.

I hand tightened the stud, put the nut on and torqued it down to 85 ft/lbs. This is the ONLY one that is doing it. I can't force it to go in any further. Should I try using the wrench to put the stud in before I put the nut on?

First pic is the stud in the middle on the intake side (3rd). Second pic is the one to the right of the middle (4th). Third pic is a comparison of both. Not the best but it's hard to capture it.

I have had the same thing happen on a 9 I put studs on using the one-by method. You will be just fine.

yeah should be fine. mine were like that. Did you stretch the studs tho, cuz its more than just 85 ft/lbs, its that and then another 90 degrees

I actually got it to go in further, like the rest after I pulled it out and cleaned the threads again. There was some dirt and oil still in the hole.

I torqued them down to 55, loosened, then 65, loosened, all the way to 85. I was told to do it this way. Seems to be holding up well... I really can't tell yet. Only has like 300 miles and a few dyno pulls.
