Where to find exhaust manifold bolts

[Buggyman]

I have nearly everything I need to bolt the heads back on my 2000 3.0. I snapped a few studs off into the heads when I removed the exhaust manifold, the shop was able to extract them without much trouble. Tomorrow is about the only day for the next two weeks that I have to work on this thing and I have everything I need but exhaust manifold bolt studs. I thought it would be easy to find at auto parts stores but so far I have struck out at every store I have been to. I have seen some that people have suggested on amazon but I was wondering if there are any easy local options that I could quickly get what I needed? I have read something about interference threads and was not sure if I could bolt any regular 8mm bolt or stud back in? Local Ford dealership has it for the price of my first born.

Thanks!

I have several BOLT stores nearby and they always have these sort of things when I need them.

Maybe the judicious use of a small hammer on the threads to make an interference fit? - only slightly serious -

I've never heard of "interference threads", and even 1/1000" of interference would make it impossible to install more than 3 or 4 threads. Machinists deal with .001-.002" cylindrical interference fits, and have to use hydraulic presses to assemble them.

Unless you have hard proof of these interference threads, I'd recommend you just get plain studs (around here, I'd look in the farm supply store) and install them torqued to spec.

^^^I've seen them from Ford. They are slightly triangular in shape rather than cylindrical. I can see why they break rather than come out after a few years of rust.
