The original Superformance GT-40 headers were developed to fit a stock OEM 351W exhaust port configuration. With the development of the SBF "Large Port" heads from Ford Racing , AFR or Dart the stock Superformance GT40 headers cause some restriction. To correct this Firefly developed these "GT40" high flow stainless steel headers. All headers are ceramic coated inside to maximize performance. Outside can be polished or ceramic coated.
