RHS® and Indy Cylinder Heads have recently teamed up to give Mopar performance enthusiasts the performance cast iron head they deserve. Designed as a cast iron replacement for small block LA and Magnum engine applications (318-360-415 c.i.), the RHS® Indy 360 X Cylinder Heads utilize patented RHS® Clean Cast Technology™ and feature a host of other improvements over the factory originals, giving your Mopar-powered street machine an easy ticket to making 400 to 550 horsepower.
The 360 X series is divided into two sub-series – the LA-X for Chrysler LA-style engines and the MA-X for Magnum applications. The LA-X Head uses the standard intake manifold and rocker shaft. It is drilled for the proper valve cover and gasket and contains both Chrylser LA and Magnum accessory holes on both ends of the head. Designed for use with the Magnum intake manifold, rocker arms, gaskets and valve covers, the MA-X Head features a Magnum pedestal large enough to enable 7/16”-14 drilling and tapping for stud-mounted rocker arms and guide plates.
