Includes one pair of intake flanges for the Buick Nailhead 264, 322 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 a light coated lightly with oil. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.
