RHS Cylinder Heads
Pro Action 360X
Cast Iron Cylinder Heads - Bare & Assembled
RHS® and Indy Cylinder Heads teamed up to give Mopar enthusiasts the
performance cast iron head they deserve. 20% More Flow!!!
A replacement for small block LA and Magnum applications, the Pro
Action™ 360 X Cylinder Heads feature a host of improvements over the
factory originals and are an easy ticket to making 400 to 550
horsepower.
The Pro Action™ 360 X is divided into two sub-series – the LA-X and
the MA-X:
The LA-X head uses the standard Chrysler LA intake manifold
and rocker shaft, is drilled for the proper valve cover and gasket
and contains both 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 pedestal
large enough to enable 7/16"-14 drilling and tapping for
stud-mounted rocker arms and guide plates.
- Cast iron replacement head designed for use with street/strip
small
block Chrysler LA & Magnum engines
- 179cc intake & 62cc exhaust runners with a 62cc combustion

- Hardened multi-angle intake (1.920") & radiused exhaust (1.625")
