Meet Stage 8 Pro Team Member Don Richardson from Zanesville, Ohio.
I run headers on an SBC 388 stroker and had the problem of the bolts coming out. I run or race at a lot of places and other racers have the same problem. I installed the Stage 8 locking fasteners on my mud truck, and the bolts do not come loose. I am telling everyone I know about these now. Thanks for this great answer to our problem.
