Includes one pair of exhaust flanges for the Big Block Ford 429, 460 hot rod motor (see motor applications below). These flanges are cut with a CNC HD (High Definition) Plasma cutter out of 3/8” Pickled and Oiled (P&O) steel. P&O material is hot rolled steel that has been dipped in acid to remove the mill scale and then lightly coated with oil. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.
Motor Application:
Big Block Ford
429 cu. in (1968-73)
460 cu. in (1968-78)
*more applications/years may work, verify before purchasing.
Ports designed to be used with 2” exhaust tubing.
These flanges are designed in CAD and are test fit on an actual head to make sure proper fitment is achieved.

Flanges, mandrel bends, collectors were nice pieces all at a excellent price. If you need nice headers build them yourself with Hell’s Gate parts. Thanks!!
