The Dilavar studs are non-magnetic. However, the barrel nuts on the end of the stud are quite magnetic, and your pick-up tool is going to contact the nut before the stud.

			When I check them using my Snap On torque wrench, click type, they "ring" a little bit when the wrench clicks indicating proper torque (23-24 ft/lb) Ping ! If they twist and do not hold torque, they are probably bad :-)

			Is your car making the telltale "playing-card-in-bicycle-spokes" noise? If it is not, you might be OK. My car, an '82, was making that noise. The resulting "while-you're-in-there" tab was far north of the $3,000 you mention. Good luck with this. It's way to easy to spend lots of money on these things.

			When I went to try my first valve adjustment, I discovered 7!!! broken studs. Previously did not hear bicycle spoke sound and car ran— not as well as after the rebuild by Dan Jacobs though.

			wow all 12 ? did you have performance issues or just get the car ? I cant belive you could drive that thing without noticing having 12 broken studs. i would be worried about corrosive exhaust gasses escaping betwen the cylinder and head and doing serious damage ..
