RHS LS1 Heads Now available

Tuesday, October 5th, 2010

Racing Head Service LS1 HeadsThe latest Pro Action™ Cylinder Heads from RHS® are affordable LS-style heads that save you the time and expense of having your new heads CNC or hand-ported. These LS cathedral port heads combine race-proven head design and Clean Cast Technology™ to create “as cast” ports that flow like they’ve already been ported.

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 (the spreading of flames in a combustible environment) while multi-angle intake and radiused exhaust seats even 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.

The new Pro Action™ Cathedral Port Aluminum Cylinder Heads for LS Applications are available in three versions: as cast P-Port with no valve job; as cast 62cc combustion chamber with 2.02″/1.600″ valves, 205cc runners; and as cast 62cc combustion chamber with 2.050″/1.600″valves, 225cc runners. Stock valve angles and centers, drilled and tapped accessory holes, and stock port locations make these heads compatible with stock applications. However, added material at the top of each head allows for upgraded valve train components, making these cathedral port heads perfect for use in everything from mild street to all-out race applications.

Part # Description Runner Chamber Valve Size In. Ex.

54301 LS Cathedral Port 205cc 62cc 2.020″ 1.600″

54302 LS Cathedral Port 225cc 62cc 2.050″ 1.600″
