The Story
97-03 Ford F-150 F-250 Expedition Aluminum Exhaust Header Gasket Set
Aluminum header gasket set built for Ford's big-displacement engines. These gaskets seal the critical junction between your headers and cylinder head—where leaks kill performance and burn fuel. Engineered to handle repeated heat cycles without degradation.
Key Features
- Aluminum construction - Resists warping under sustained high heat, maintains seal integrity longer than composite alternatives
- Full set configuration - All gaskets needed for complete header installation in one box, no hunting for individual pieces
- OEM-compatible design - Matches factory gasket dimensions and bolt patterns for direct fitment
Specs
- Material: Aluminum
- Configuration: Complete header gasket set
- Condition: New
What's Included
- Aluminum exhaust header gasket set (all pieces)
Frequently Asked Questions
Do I need to clean the header and cylinder head surfaces before installing these gaskets?
Yes. Scrape off all old gasket material and carbon buildup from both mounting surfaces. A clean, flat surface is the only way these gaskets seal properly—any debris or residue will cause leaks immediately.
What bolts do I use to clamp the headers down?
The set includes the gaskets only. You'll need the factory header bolts from your vehicle—refer to your service manual for torque specs and bolt diameter. Have those on hand before you start.
Can I reuse these gaskets if I pull the headers off later?
No. Aluminum gaskets compress and conform to surface irregularities—once removed, they won't seal again. Plan on fresh gaskets every time you pull your headers.
