Stainless Headers Mfg. header flange kits come with the stubs formed and welded in to make custom header fabrication easier. Each flange has a 2" long stub welded on the mating surface and stitch welded on the exterior for bolt clearance. The flange is then surfaced for a superior gasket seal. Made from an American made mild steel and purge tig welded, these flanges with stubs, will get your header project off to a great start.

This round port flange fits the LS1-LS3 slightly oval port configuration.
Depending on the tube size combination, the tube stub may go thru the flange port or sit on top of the flange-call for details.
