Small Block Chrysler W5 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. These header flanges are made for the W-5 small block mopar heads. These flanges also fit the 360-1 and 360-2 heads from Indy Cylinder Heads. The flanges have the same bolt pattern as W2 heads, but with a raised exhaust port.

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.
