Stainless Works Small Block Chevy Squared Oval Port Header 304SS Exhaust Flanges 1-7/8in Primaries

If you're building a custom exhaust for your Small Block Chevy, these header flanges from Stainless Works are a solid starting point. They're specifically shaped for squared oval ports and designed to work with 1-7/8 inch primaries, giving you a precise fit for your fabrication project.

These flanges are laser-cut from heavy-duty 3/8 inch thick 304 stainless steel. This material choice is important because it resists warping even when exposed to the high heat of exhaust systems. The thickness also adds to their durability, ensuring they hold up well during the welding and assembly process.

You get a pair of these flanges, ready for your custom header build. They come with a limited lifetime warranty from Stainless Works, so you can be confident in their construction.
