Chevrolet Performance LSX-LS9 Cylinder Head
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.
Additional features include:
Uses 11mm (10) and 8mm (13) head 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)
Extra material cast in the port areas to accommodate professional porting
Valve guides for 8mm valve stems, except DR & CT
Racing-specific LSX-DR (Drag Racing) and LSX-CT (Circle-Track) heads feature
raised runner designs and other unique features designed to maximize performance
at the track.
