Frequently Asked Questions
Will this bolt to my existing manifold mounting points?
This header is engineered for big block V8 top-mount applications. Confirm your engine block has factory top-mount boss locations before ordering—test-fit is essential since exhaust port alignment varies between engine generations.
Do I need to weld this or does it bolt together?
The header assembly ships complete. Connection method to your exhaust system depends on your build—whether you're using flex hose, cast elbows, or custom piping is up to you.
Can I run this straight out of the box or does it need prep?
Stainless steel arrives bare metal and ready to install. If you're concerned about thermal wrap or heat shielding, those are separate purchases based on your engine bay configuration.
