Stainless Works Big Block Chevy Round Port Header 304SS Exhaust Flanges 1-7/8in Primaries

If you're building a custom exhaust system for your Big Block Chevy, these header flanges are a solid starting point. They're designed to help you fabricate a clean, leak-free connection for your exhaust primaries. These are specifically for the round port style heads common on many Big Block Chevy engines.

These flanges are laser-cut from a hefty 3/8 inch thick piece of 304 stainless steel. That thickness is key because it helps prevent the flange from warping when things get really hot, which is common with these big engines. The 304 stainless also offers good resistance to corrosion over time. You get a pair of flanges, ready for your custom header build.
