Stainless Works BBC Round Port 304SS Exhaust Flanges 2-3/8in Primaries (Raised Port Heads Only)

If you're building a custom exhaust system for a Big Block Chevy with raised port heads, these Stainless Works header flanges are a solid choice. They're specifically made for the round port design and are sized for 2-3/8 inch primary tubes, ensuring a good fit for your custom headers.

These flanges are laser-cut from a substantial 3/8 inch thick piece of 304 stainless steel. This heavy-duty construction helps prevent warping, even when things get really hot under the hood. The 304 stainless steel itself is well-known for resisting corrosion, so these should hold up well over time. You get a pair of flanges, ready for your fabrication project.
