Small Block Ford Z304 2" & 3" Mild Steel Header Flange

Precision laser cut form 3/8" thick mild steel, our header flanges are manufactured in the U.S. and are machine surfaced. These header flanges are specifically made for SBF-W heads with either a 2" bolt spacing, or aftermarket heads with a 3" bolt space pattern. This Z304 pattern is also found on a number of AFR small block Ford heads.

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.
