These small-block Chevy 265-400 V8 headers are designed for optimum performance in a variety of 1935-1948 fat-fendered street rod and pickup applications. Perfect for Gasser-style rods and drag cars, the ceramic coated headers have long primary tubes that curve over the frame and through the fender wells. You must cut the inner fender panels to make them fit. These fender well, ceramic coated headers provide superior performance and durability.

  1. Can be used with most oil filter system or transmission and starter combination.
  2. Fits most angle plug heads.
  3. Check motor mount position before ordering.

AHC coated headers will burn and be damaged at exhaust temperatures above 1300 degrees. An excessively lean fuel mixture can generate exhaust temperatures over 1700-1900 degrees. If the coating is burned (which will look like a dull gray) due to a lean condition, it is not warrantied, but the headers can be recoated.
