Ravenworks’ 5.7L 3D Contoured Hemi Header Flanges

37If you’re at all intrigued by the prospects of a HEMI engine, here’s another incentive to using it in your next swap project: Ravenworks‘ latest, the 5.7L 3D contoured Hemi header flanges. Made from 1/2″ 304 stainless steel, these things were built to last, and offer the ability to create the perfect set of headers to fit your vehicle. 

Official Release:

Ravenworks has added another highly sought after product to their growing catalog, this time aimed at the late-model Hemi crowd. The new Hemi platform from Chrysler is growing in popularity and as people start swapping them into other cars they have found few flanges out there for making headers. Ravenworks has stepped-in to fill the void with a product designed and manufactured in-house.

The new header flanges are made from ½” 304 Stainless Steel and features contour-porting, saving the builder from having to shape a round tube end to match the squared port of the new Hemis. Another feature is the stepped tube locator which allows better weld penetration and tube fitment.

“We are committed to our new Hemi program and will continue to develop top-quality parts that are well-engineered. This flange is one of those products that was missing from the market and it’s already been well received in the Mopar community.” Says Bob Schreiber, product designer for Ravenworks.


  • Made from 1/2″ thick 304 stainless steel

  • Stepped tube locator allows better weld penetration and tube fitment
