Descriptions:

  • Mounting style: 3 bolts.
  • These "Block Hugger" headers will fit in tight spaces and come with bolts, gaskets, and a pair of reducers for easy installation.
  • These headers are designed for straight-plug cylinder heads. You may encounter interference problems with angle-plug heads.
  • Block hugger style headers are meant to be used where space for long tube headers isnt available due to steering and cross-member clearance issues.
  • Tubing has been optimized for the 5.0L (305ci), 5.3L (327ci), 5.7L (350ci), and 6.6L (400ci) engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity.
