EQ Cylinder Heads

The EQ magnum and LA series cylinder heads are designed for use with their corresponding intake manifold, rocker arms, and valve covers. The EQ 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. As a cast iron stock replacement head, the EQ 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 over 400 horsepower and feature 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 EQ Cylinder Heads also come with an extra thick deck surface to enable angle milling for compression. Contact Southeast Performance for special pricing and upgrades.
