Superformance headers were developed to fit a stock OEM 351W exhaust port configuration.  With the development of the SBF high flow Ford Racing "GT40" or similar heads, the stock Superformance headers cause some restriction.  To correct this Firefly  developed these high flow ceramic coated stainless steel headers with the hour glass flange configuration as shown below.
