  • Extending the performance range of the LSX platform are Chevrolet Performance's new, 6-bolt LSX cylinder heads. Many are capable of flowing more than 400 cfm and their 6-bolts-per-cylinder clamping design gives them bomb-proof strength. Your horsepower-building potential is nearly unlimited with LSX heads. These aluminum masterpieces of performance feature port and chamber designs based on popular and performance-proven production-style heads, such as the LS3/L92 and LS7 heads. They are easily identified by the engraved LSX logo on the ends.

  • All LSX heads are made of 356-T6 aluminum and feature a 5/8'' thick deck that allows plenty of room for builder-specified combinations.
  • Extra material cast in the port areas to accommodate professional porting
