Do I need to replace the manifold bolts when I install this?

The gasket uses your existing bolts — no new hardware required. Hand-tighten first, then torque in a cross pattern to seat the gasket evenly. Refer to your service manual for the correct torque spec.

Should I clean the mounting surfaces before installation?

Yes. Scrape away old gasket material from both the manifold and cylinder head surfaces with a gasket scraper or soft putty knife. A clean, flat surface ensures the new gasket seals properly on the first try.

What if I notice exhaust leaking at the joint after installation?

The gasket may not be seated fully. Remove the manifold, clean both surfaces again, and reinstall — this time tightening bolts in a diagonal pattern to apply even pressure across the entire gasket face.
