This is a powerful cast iron replacement head for Small Block LA applications.


 This LA-X head uses the standard "LA" intake manifold and  shaft style rocker system. It is drilled for the proper valve cover and gasket and contains both Chrysler LA and Magnum accessory holes on both ends of the head. This head is designed for use with 8mm intake (1.92” diameter) and exhaust valves (1.625” diameter).

 A cast iron replacement, the RHS™ Indy 360 X Head series is designed for both Small Block LA  applications (318-360-415cid). With a host of additions and improvements over the factory originals, these heads are an easy way to get 400 to 550 horsepower out of your Mopar-powered street machine. Features of these impressive heads include 179cc intake and 67cc exhaust runners, a 62cc combustion chamber, multi-angle intake and hardened radiused exhaust valve seats, an improved valve guide design and a highly efficient water jacket to prevent engine hot spots. The 360 X Cylinder Heads also come with an extra thick deck surface to enable angle milling for compression.  

NOTE: To use these heads on a magnum block, the block must have the L.A. shaft oil passages. These are located between the #1 and #3 cylinders and between the #2 & #4 cylinders.
