Review on 🔒 Stage 8 8916A 1" Locking Header Bolt Kit: Ultimate Fastening Solution for Secure and Reliable Performance by Mike Diaz

I bought these for my manifolds. had to install it and one screw was machined incorrectly. The ring could not be attached to it, it was too short. Of course, Amazon has a quick return policy. So when you buy them, open them up and inspect them all, just like a normal factory should. gratitude
