Pontiac V8 (all except 301) D-Port Stainless Header Flange- 1/2" Thick

Precision laser cut from 1/2" 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 V8 Pontiac heads, 326-455 CID (all Pontiac V8's except 301).

Port Size: 2" for 2" size tubing

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 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.
