Review on 🔩 ARP 4001201 Header Stud and Bolt by Mark Colbert

ARP is always of the highest quality. The 12 point bushings make it much easier to tighten the bolts to the correct torque, especially since I have manifolds on my SBC engine. I used to have hex head bolts before I bought them and I couldn't find a wrench to tighten them because they were too close to the header pipes. I had to use an open end wrench and could barely tighten them enough. Not with those ARP bolts anymore.
