I would be worried about stripping the heads on those bolts. If you ever needed to get them off, that would suck. I guess you could always burn them off.
I know it's a tight fit. These are Kooks clones, so I'm pretty sure I've experienced what you will with these headers. Personally, I would recommend a conventional bolt design, or least one that would take regular wrench as well as the allen wrench. The Percy's bolts I mentioned have an allen screw in the middle to lock them, if you're interested in a locking bolt.

I started out using studs. I hope you have tiny hands, they're a bitch to turn in. The ARP studs have a balled end making them a real bitch to turn into the head with the header in place. The 100-1412 has hex nuts which might not clear the primarys plus getting a wrench on them is a pure hell.
Really guys, 12 point headed stainless bolts are the best for this application. Steel bolts or nuts will eventually have some corrosion issues.
This is the ONE place in an automobile that I use stainless. It's just too soft and strips and galls easily.

I did a little measuring and testing with bolts I got at my house and getting the hex on there with the current clearnce shouldnt look too bad.....I'll just have to wait n see
