Pro Action Cathedral Port Aluminum Cylinder Heads for LS1 Applications deliver improved power and performance. A race-proven head design and Clean Cast Technology create "as cast" ports that flow like they've already been ported. Now, these revolutionary heads are available fully assembled with premium-quality COMP Cams valve train components. Every fully assembled RHS head utilizes COMP Cams one-piece, stainless steel valves, state-of-the-art Beehive or high performance dual valve springs (dependent on your camshaft selection), steel, tool steel or titanium retainers, bronze valve guides and 7-degree, machined steel valve locks. RHS Pro Action Cathedral Port Aluminum Cylinder Heads for LS Applications are engineered with highly efficient combustion chambers that increase power and torque by improving airflow and flame propagation while multi-angle intake and radiused exhaust seats further improve airflow. Their durable 355T6 aerospace-grade aluminum alloy construction is lightweight and increases cylinder head life and strength, while high capacity water jackets generate greater thermal conductivity for cooler, more efficient engine operation. When combined with COMP Cams valve train components, you get the most advanced fully assembled cylinder head on the market today.
