This may seem like a PITA, but it is well worth the headache. First off let me say that I have tried all the trick header bolts known to man and they all work for awhile and then it's back to the same old problems. For this old drag racers trick you can use any type header bolt, but I used the type with the allen wrench type head on them. You will need the following....

Header bolts and a couple nuts
Safety wire
Drill and drill bit
Vise

Take your header bolt and screw a couple nuts on the threads. Place it in a vise with the head above the vise jaw. Drill a small hole all the way through the head of the bolt. Repeat for every header bolt. Clean up any burrs on the header bolt. Install the header bolts and torque them down to spec. Run the engine and get things nice and hot. Let it cool and retorque the header bolts. Thread the safety wire through the holes in the header bolts. Three times is about maximum depending on how big the head of the bolt is. Connect them all or two at a time. How you do this is purely up to you, there is no right or wrong way. When the header bolts try to back out they will not be able to as the safety wire and the other header bolts that it's ran through will prevent it. If you run the safety wire over the top of a header tube it will burn the wire or it may become corroded enough that it gives out and breaks. This takes a long time. Just remove it and re-thread the safety wire after checking the torque on the header bolts. I did this on my '78 Z28 3 years ago and it is still holding. I do not drive it every day however.

Fear....Tastes just like chicken!
