Perfect for Big-Inch Motors!

Designed to provide an even greater intake charge than the Sportsman II, World's Motown 220 clearly rates as the ultimate small block cast iron head. It features the latest high tech 64cc chambers and RightCast 220cc runners to provide a combination of excellent flow and high velocity. With high-flow ports and standard intake valves, World Products Motown 220 heads are the ideal compliment to large displacement small blocks (383ci and larger).
