Do I need to clean the mounting surfaces before installation?

Yes. Wire-brush both the cylinder head and manifold sealing surfaces to remove carbon buildup and old gasket material. A clean, flat surface ensures a tight seal and prevents exhaust leaks.

What bolts does this gasket use?

Mounting method not specified—check your vehicle's service manual for the correct bolt spec and torque sequence. Most applications use standard manifold bolts already in your truck.

Can I reuse the old bolts, or do I need new ones?

Exhaust manifold bolts can seize from heat cycling. If the old bolts come out intact and aren't corroded or stripped, they're usually fine to reuse. If they're stuck or damaged, replace them with new hardware from your parts supplier.
