Features & Benefits:

This is the aftermarket’s only high performance LS7 head with a raised intake runner design specifically engineered to accommodate production and aftermarket LS7 intake manifolds and valve train setups. The 12° valve angle (flatter piston to valve angle) and unique .220″ raised intake runners provide a better line of sight into the cylinders and allow for an improved short turn. In addition, the custom CNC-machined runners optimize volume, atomization and velocity.

The 355T6 aerospace-grade aluminum alloy heads also feature the popular LS 6-bolt head design that makes them compatible with both the RHS® LS Race and GM LSX Blocks. This design also increases clamping capacity to improve cylinder head gasket retention on high horsepower and boosted applications. All of this, with the addition of a .750″ thick deck surface, increases the integrity in high cylinder pressure applications.

A reinforced solid rocker rail with extra bolts was engineered for shaft mount rockers to provide increased rigidity and valve train stability, while the raised .400″ valve cover rails provide clearance for aftermarket rocker systems. And finally, the raised runner and rolled valve angle increase overall flow capability. These features, coupled with an improved water jacket design, make this an ideal head for both small and large cubic inch, hardcore street applications.
