RHS® Pro Elite™ Aluminum Cylinder Heads For LS7 Applications

Memphis, TN - RHS® has released the aftermarket’s only high performance LS7 head that features a raised intake runner design specifically engineered to accommodate production and aftermarket LS7 intake manifolds and valve train setups.

 are designed with a 12-degree valve angle and unique .220" raised intake runners to provide a better line of sight into the cylinders and allow for an improved short turn. In addition, custom CNC-machined runners optimize volume, atomization and velocity. Engineered from 355T6 aerospace-grade aluminum alloy, the heads feature the popular LS 6-bolt head design, making them compatible with both the RHS® LS Race Block and all OEM or aftermarket GM LS-type blocks. The design also increases clamping capacity to improve cylinder head gasket retention on high horsepower and boosted applications. These features, and a .750" thick deck surface, increase integrity in high cylinder pressure applications. In addition, the Pro Elite™ Heads have a reinforced solid rocker rail engineered for shaft mount rockers to provide increased rigidity and valve train stability. Raised .400" valve cover rails provide clearance for aftermarket rocker systems, while the raised runner and rolled valve angle increase overall flow capability. These features, coupled with an improved water jacket design, make them ideal heads for both small and large cubic inch, hardcore street applications.
