Swapping headers on your Ford with a 4.6L or 5.4L modular engine? You're gonna need good bolts. This BBK Performance bolt kit gives you 16 high-quality M8 x 1.25 x 30mm bolts that are perfect for the job. Whether you're installing shorty headers, full-length headers, or even putting the stock manifolds back on, these bolts are made to fit and hold up.
Why bother with a specific kit? Because header bolts take a beating from heat and vibration. Cheap or worn-out bolts can stretch, rust, or snap, leading to exhaust leaks and headaches. These are built to be stronger and more reliable. BBK is a trusted name in performance parts, so you know you're getting something that'll work.
The kit includes everything you need for both sides of the engine. Just make sure your application matches (Ford 4.6L or 5.4L modular V8). Always use a good thread lubricant or anti-seize during installation to make future removal easier. It's a small but crucial part of your exhaust upgrade—don't reuse those old, tired bolts. Get this kit and do it right.
