  • Compact design
  • OEM-style exhaust pipe connection
  • 3/8” thick flanges w/ oval 1.29" x 1.67 port configuration
  • Header bolts and exhaust gaskets are included
  • Collector reducers are not included but are offered below
  • May require modifications to accommodate knock sensors in some applications

Header Dimensions (GIF)



  • 1992 and later LT-4 engines
  • Compact design will fit a wide variety of early street rods
  • Will not fit 1955-1957 Chevys, Camaros, Chevelles or other modern cars with crossmembers under the two center exhaust ports

NOTE: Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperature. Please note that the finish of the header when the engine is started, will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished back out when utilizing Blue-away or Simi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.  

Some parts are not legal for use in California or other states with similar laws/regulations
