Small Block Chevy Stainless Header Flange

Precision laser cut form 3/8" thick 304 Stainless Steel, our header flanges are manufactured in the U.S. and are machine surfaced. These header flanges are specifically made for stock small block chevy heads. Many aftermarket heads also utilize the stock small block Chevy bolt pattern.

Port Size: 1 5/8" and 1 3/4" port sizes available

1/2" Thick Flanges available for boosted, nitrous, or high horsepower applications. They perform great under the heat, and can significantly reduce warping during a header build.

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 250 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.

Flanges sold separately.
