Includes one Straight Lake Header Kit for the Ford Y-Block 239, 256, 272, 292, 312 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 to prevent rusting. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.
Kit includes:
1 pair – 30″ long steel megaphones (1-5/8″ inlet & 3-1/2″ outlet) – 4″ outlet available (Include in order notes)
