Description:
These Performer RPM Chrysler Magnum heads give substantial performance improvements for street/strip and off-road performance use. They offer an easy bolt-on engine upgrade with substantial out-of-the-box performance gains. Stock Magnum intake and exhaust flange and port locations make these heads an ideal choice for use with stock equipment as well as the new RPM Air-Gap manifold. These heads feature a slight increase in compression over the factory heads, offer more flow than stock, and accept adjustable aftermarket rocker arms. These heads are available in bare or assembled versions; hardened pushrods are required.
