Overall Assessment

Customers appreciate the high quality and perfect fit of our header flanges, particularly for tailor-made AV8 builds. These components are praised for their precise cut, exact alignment with bolt patterns, and the ability to support substantial welding without warping. The thickness and robustness of the part contribute to its considerable durability, outperforming competitor options. Few suggested improvements include providing a smaller tube diameter variant and improving deburring for smoother sides. Despite these minor points, our header flanges come highly recommended by users for their superior craftsmanship and fit.

Header flanges were about 1/4" thick so you can really weld anything to them and they are not going to warp at all.
