Pontiac 400/455 Ram Air IV Style 1/2" Thick Stainless Turbo Header Flange

Precision laser cut form 1/2" thick 304 Stainless Steel, our turbo header flanges are manufactured in the U.S. and are machine surfaced. These turbo header flanges are specifically made for Ram Air IV style Pontiac cylinder heads. Many aftermarket heads also utilize the same bolt pattern, including the Edelbrock Performer, and the Kauffman Racing Engines High Port heads.

Port Size: 2" round port

The 2" port size flange utilizes slotted end bolt holes to gain easier bolting ability under high temperature welding applications.

The large port size is great for turbo header builds when a heavy wall tubing or schedule 10 pipe is looking to be used, while still maintaining a high-velocity, smaller inner diameter.

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.
