Designed for 1992 & later 5.2L (318ci) and 1993 & later 5.9L (360ci) Chrysler Magnum V8s. The Performer RPM Chrysler Magnum heads give substantial performance improvements for street/strip and off-road performance use.
They offer an easy bolt-on upgrade for these modern engines with substantial out-of-the-box performance gains. Stock Magnum intake and exhaust flange and port locations make this an ideal choice for use with the RPM Air-Gap manifold 350-7577.
These heads feature 180cc intake ports and 75cc exhaust ports with 58cc combustion chambers for a slight increase in compression over the factory heads. 2.02'' intake and 1.60'' exhaust valves with 11/32'' stems offer more flow than stock and they accept adjustable aftermarket rocker arms.
