Precision laser cut from 3/8" thick mild steel, our header flanges are manufactured in the U.S.A. and are machine surfaced. These header flanges are specifically made for the 304-401 c.i. AMC V8 engines.
Port Size: 1.838"
Preformed flange stubs are 2"-3" long, and have one end perfectly formed to the port shape of the flange using the appropriate tubing size for that port. This can drastically decrease overall build time. If you have questions on sizing or other options, talk with one of our techs for more information.
We carry over 250 different header flange designs, so if you don't see the flange you're looking for, talk with one of our tech reps about custom header flange cutting.
