Jeep 4.0 Redesigned 1/2" 304 Stainless Steel Header Flange 1.625"(Slip in) Primary tube.
Newcomer racing corrected and redesigned "True round port" 1/2" 304 Stainless Steel Header Flange. This flange will accept a 1.625"(1-5/8") Slip in the port or a 1.75"(1-3/4") flush welds to the outside flange. *** Other items to compliment this custom header flange is our new designed .500"(1/2") Stainless Steel Intake/Exhaust Flange Winged and Non-Winged Pinch Washers that can be clocked to reach out and grab that surface that a normal stock washer will not reach. (Matching Copper gaskets are currently in production!!!) ***NOTE- These flanges will need to be bolted flat to a head as a JIG during mock-up and welding your header to assure good fitment. Flanges will bow naturally but they will lay out flat once bolted down***
