RHS® LS7 Cylinder Heads are the aftermarket’s first high performance LS-style head to feature a raised intake runner design that fits both stock and aftermarket LS7 intake manifolds and valve train setups. These RHS Aluminum Cylinder Heads are designed with a 12° 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. The heads also utilize the popular LS 6-bolt head design, making them compatible with both the RHS® LS Race Block and most GM LSX Blocks. The raised runner and rolled valve angle increase overall flow capability while an improved water jacket design improves thermal conductivity. • Standard LS 6-bolt head design is compatible with the advanced RHS® LS Race and popular GM LSX Blocks • Increased clamping capacity greatly improves head gasket retention in high horsepower and boosted applications • .750" Thick deck surface increases integrity; reinforced solid rocker rail increases rigidity and stability; 355-T6 aluminum withstands race conditions • .400" Raised rail works with aftermarket rockers; .100" raised exhaust port allows use of stock and aftermarket manifolds • Can be used in small and large cubic inch, hardcore street applications These castings are great before we even start, but we build them to be the best available LS Based heads for the money!!
