Default How to keep header bolts from coming loose?

I'm tired of tightening the header bolts every couple hundred miles. I even lost one of the passenger side bolts one time.

I know that several approaches exist (Nordlock washers, safety wire, stage 8 locking fasteners etc). Is there something that actually works?

I have ARP bolts, and then drilled a hole in each bolt head, then threaded lockwire between each pair of bolts. Been told it works, havent tried it in anger yet.

I had Stage 8 lockers on my FE for over 8 years with none ever coming loose.

I just switched to these and have found them great so far. Also, easier to install than some for the tight spots like the #8 cylinder.

For an FE use 1" long ARP bolts, not the cheap 3/4". Use antiseize. Never a problem.

ARP sells a stainless 1" bolt set that is pre-drilled for safety wire. You can get them from Summit. Ask for the NASCAR pack.

Thanks to everyone for their suggestions! I think I'll give the stage 8 bolts a try.

I screw studs (SS) into the head and use a serrated faced nut with lock washers.
Much easier to remove and install the headers if need be as well.
