Precision laser cut from 3/8" thick 304 stainless, our header flanges are manufactured in the U.S. and are machine surfaced. These header flanges are specifically made for all big block Ford engines with 385-series heads from 1968-1997, with the exception of the Cobra Jet models.
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.
Port Size: 1.868", 2.091", 2.254"
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.
