What You Get
Key Benefits
- 1-1/2 inch primary tubes increase exhaust flow velocity and reduce back pressure compared to factory manifolds
- Bolt-on installation with included hardware eliminates the need for welding or engine modifications
Why Buyers Switch
Problems It Solves
- Factory exhaust manifolds restrict flow and create high exhaust gas temperatures under load
- Mild steel manifolds rust at the flange and gasket interface within a few years of use
- Universal headers require cutting, welding, and custom fitting, increasing installation time and cost
- Poorly machined flanges lead to exhaust leaks and inconsistent torque patterns

Comparison
Compared With The Alternatives
| Factory exhaust manifold | The stock manifold is heavier and restricts flow with narrow passages; this header improves flow and increases engine output by 10-15 HP |
|---|---|
| Universal header kit | Universal headers require cutting, welding, and fitting; this one bolts on directly without modification |
Installation
Use Guide
- Confirm the engine is a Small Block Ford 289-302 block and not a 351W or later model
- Remove the factory exhaust manifold and clean the engine block flange surface before installation
- Use new metal gaskets and bolts-do not reuse old components
- Torque flange bolts evenly in a crisscross pattern to maintain sealing face flatness
- Recheck bolt torque after the first heat cycle to prevent leaks
