Pontiac 301 Turbo V8 Mild Steel Header Flange

Pontiac 301 Turbo V8 D-Port Mild Steel Header Flange

Precision laser cut from 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 stock V8 Pontiac 301 heads. These are specific to the 301 V8 heads, as there is an additional bolt hole above the center exhaust ports, not found on other Pontiac V8 exhaust flanges.

Port Size: For 1 3/4" header tubes

Preformed Flange Stubs are 2" 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 450 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.
