Do I need new bolts to install these gaskets?

Gaskets alone don't require new hardware, but if your existing header bolts are corroded or damaged, swap them out. Most installations reuse stock fasteners if they're in decent shape.

Should I apply sealant or gasket dressing to these?

These gaskets are designed to seal on their own without additional product. Skip the RTV or dressing — over-application can create a mess and reduce seal quality.

What's your return process if the gaskets don't seal properly?

Test-fit and inspect the gasket surfaces on both the header and manifold before final installation. Warped or damaged mounting surfaces are a common cause of leaks. If the gaskets are defective upon arrival, contact our support team within 30 days with photos.
