  • Block flange on these headers is 5/16" thick
  • Collector Flange Outlet: 2-1/2"
  • Not for use with stock wishbone front suspension

Includes block gaskets, collector gaskets and a pair of companion 2-1/2" flanges for beginning the exhaust system (companion flanges fit 2-1/2" pipe).

Warranties

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 warranted, but the headers can be recoated for a fee.
