When installing headers should you be using locking fasteners?

Question

I am probably going to have a shop install my headers, should I tell them to use locking fasteners or buy them and give it to them to use or do I not really need to be using locking fasteners?

Answer 1

Safe yourself lots of future work and install locking fasteners.  Look at Stage 8 (if I remembered the brand) at Summit or Jegs on line. They work very well.

Answer 2

There are special fasteners for headers, the shop where you are having yours installed should know which ones to use. they are pretty good to keep them in place.
