Buick Nailhead (Baby) 264-322 Straight Lake Header Kit



Includes One Straight Lake Header Kit 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.


Kit includes: 

1 pair – 30″ long steel megaphones (1-5/8″ inlet & 3-1/2″ outlet) – 4″ outlet available upon request
