|---|---|
| Mild steel aftermarket header | Mild steel is cheaper but corrodes at the flange and gasket surfaces; stainless steel lasts longer in harsh conditions |
| Universal header kit | A universal kit requires cutting and welding to fit; this one bolts on without modification |

- Allow the engine to cool completely before removing the factory headers
- Replace the factory gaskets and use new screws to ensure a leak-free seal
