Chrysler 5.7L Hemi Square Port Mild Steel Header Flange

Precision laser cut from 3/8" thick Mild Steel, our header flanges are manufactured in the U.S. and are machine surfaced. This Square-port header flange is designed for the Gen III Mopar HEMI 5.7L cylinder heads with square ports. These are the non-Eagle style cylinder heads. Earlier model gen III hemi heads will typically have a round or square exhaust port, though bolt patterns remain the same.

Preformed Flange Stubs are 2"-3" in length, and are formed to perfectly fit the non-round port in the flange. Stubs drastically reduce overall build time and increase builder's efficiency.

We carry over 450 different header flange designs, so if you don't see the flange you're looking for, talk with one our tech reps about custom header flange cutting.
