    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.

    Features include:
  • 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
  • Uses 11mm (10) and 8mm (13) head bolts
  • 6-bolt per cylinder bolt pattern
  • LS7 style rectangle port design
  • 12 degree valve angle
  • Uses LS7 rocker arms/LS7 bolts
  • Accommodates production valvetrain components (except for Drag Race and Circle Track heads)
  • Includes premium beehive-type valve springs (except for Drag Race and Circle Track heads)
  • Valve guides for 8mm valve stems (except for Drag Race and Circle Track heads)
