Best of the Best:Engine Performance Parts
World Products' Motown 220 cylinder heads are designed for small-block Chevy engines. Because the 220cc intake ports flow plenty of air, the Motown heads are best suited to engines that are moderately modified with a performance camshaft and induction upgrades, or are more than 383 ci in displacement. The Motown heads are cast iron, using World Products' RightCast technology, which ensures that the intake, the exhaust ports, and the combustion chambers retain their designed shape during the casting process. The heads are available with either 64cc or 72cc combustion chambers, as well as straight or angle-plug configurations. The Motown heads are available as complete assemblies, including Manley stainless steel valves, valve springs, and screw-in rocker arm studs, or as bare castings with screw-in rocker arm studs.
