Cast in Australia with premium materials and machined to exact tolerances, the EQ Magnum cylinder heads accept production or aftermarket valvetrain components, intake manifolds, and exhaust manifolds/headers. EQ Magnum cylinder heads provide an affordable alternative to more pricey aftermarket aluminum versions while not giving up power for racing or severe street usage.
Two versions of the EngineQuest Magnum head are available to fit a wide variety of applications:
EQ Part #CH318B for 1992–2004 Chrysler 318/360. Heads are machined for a pre-1990 LA-style intake manifold bolt pattern that still uses all Magnum rocker parts. The EQ CH318B is also approved as a stock replacement for the IMCA Hobby Stock and SportMod divisions.
EQ Part #CH318A. Identical to the CH318B but machined for the production 1992-2004 5.2L and 5.9L Magnum intake manifold bolt pattern.
EQ’s Magnum cast-iron cylinder heads will also retro-fit on virtually any 1967 or newer Chrysler small-block with ease. No need to do the junkyard crawl or spend weekends going to swap meets looking for rusty head castings. The EQ Magnum heads are engineered to outperform any production cylinder head including the infamous 1968-1971 Chrysler 340 “X” casting.
