Do these headers come with gaskets and bolts?

Header assembly only — gaskets and fasteners are not included. You'll need to source gaskets and header bolts separately to match your engine block's specifications.

Will these bolt directly to my engine, or do I need modifications?

Mounting compatibility depends on your exact engine configuration. Test-fit before committing to any permanent installation. Some applications may require exhaust manifold adapter plates or collector modifications.

Do I need to paint or coat these before installation?

Stainless steel won't rust, so paint isn't required for protection. If you want a specific finish, ceramic coating or high-temp paint can be applied before install — just ensure it's cured completely before engine startup.
