Do I need new gaskets and bolts?

The header assembly is delivered without gaskets or fasteners. You'll need to source OEM or equivalent gaskets rated for high-temperature exhaust, plus stainless steel bolts rated for manifold duty — these are not included with the header.

Can I weld this header if it cracks later on?

Stainless steel can be welded, but it requires tig welding and specific filler rod. If the header fails, welding is possible but may compromise that section's structural integrity under sustained heat — replacement is the safer long-term choice.

Will this bolt directly to my stock exhaust manifold location?

This header is designed to use factory mounting points on the V8 engine block. Test-fit the header assembly before final fastening — factory hole alignment can vary slightly between individual vehicles.
