Will these headers fit without modifying my engine bay?

The hugger design is tucked to fit the factory big block bay. Test-fit before final installation to confirm clearance with your specific engine setup and accessories.

Do these need any prep before installation?

Stainless steel headers ship ready to bolt on—no paint or coating needed. Inspect for any shipping marks and clean with a soft cloth before mounting.

What fasteners do I need to secure these?

Mounting hardware is not included—use OEM bolts or high-temp fasteners rated for header applications. Refer to your vehicle's service manual for torque specs and bolt sizing.
