Stainless Header Flange For F.H.O Millennium/High Port Hemi Heads

Precision laser cut from 3/8" thick 304 Stainless Steel, our header flanges are manufactured in the U.S. and are machine surfaced. These header flanges are made specifically for the FHO (For Hemis Only) Millennium/High Port Heads. These flanges fit other aftermarket 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.
