ON THE BENCH: ENGINEOUEST MAGNUM HEADS

摘要

EngineQuest's Magnum heads (PN 318B) and its LA-Series counterpart (the 318A) are iron replacement-style cylinder heads designed to bolt in place of tired or cracked originals. Fortunately, EngineQuest invested the effort to substantially improve on the factory design through a process of detail refinement rather than radical design changes. What results is a head that does double duty, serving as an economical replacement for OEM, while supporting the needs of a low-cost mild performance unit.
