Stainless Works Small Block Chevy Squared Oval Port Header 304SS Exhaust Flanges 1-3/4in Primaries

If you're building a custom exhaust for your Small Block Chevy, these header flanges are a solid starting point. They're designed specifically for the squared oval port heads found on many Chevy V8 engines and are meant to work with 1-3/4 inch primary tubes.

These flanges are laser-cut from a heavy-duty 3/8 inch thick piece of 304 stainless steel. That thickness helps prevent them from warping when they get hot, which is crucial for a good seal on your exhaust. The 304 stainless steel itself is well-known for its resistance to corrosion, so they'll hold up well over time. You get a pair of these flanges, ready for your custom header fabrication project.
