Includes one pair of exhaust flange for the Chevrolet 6 cylinder 194, 215, 230, 250, 292 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 a light coated lightly with oil to prevent rusting. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.

6 – 2″ OD, 0.065″ wall plain steel (not aluminized!) 70 degree mandrel bends
