Includes One Straight Lake Header Kit for the Ford Flathead V8 hot rod motors (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.
Kit includes:
1 pair – 30″ long steel megaphones (1-5/8″ inlet & 3-1/2″ outlet) – 4″ outlet available (Include in order notes)
1 – 1-5/8″ OD, 0.065″ wall plain steel (not aluminized!) 180 degree mandrel bend
4 – 1-5/8″, 0.065 wall, 10″ long plain steel tubing
1 pair – 3/8″ thick exhaust flanges – specific motor application listed below

I’m very pleased with the headers, nice quality, exactly what I though I was buying, that doesn’t happen very often anymore. Thank you for a great product.
