Product Description

Dodge/Jeep 5.2/5.9 Magnum Fully Ported Indy 'X' Heads (formerly RHS) W/ 2.02"/1.620" Stainless Steel Mopar Performance Valves.

These 2.02 heads are fully ported, intake and exhaust, including unshrouded intake and exhaust valves in the combustion chamber.

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

This head is designed for use with the Magnum intake manifold, rocker arms, and valve covers. The MA-X head features a Magnum pedestal that is large enough to enable 7/16”-14 drilling and tapping for use with stud-mounted rocker arms and guide plates. A cast iron replacement, the 360 X Head series is designed for Magnum 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.
