MOTOWN   CHEVY Iron Heads

Designed for use in racing applications where cast iron heads are
mandated or for larger displacement small block street-type engines,
World’s 220cc intake MOTOWN heads are the ULTIMATE cast iron SBC
head.

Employing RightCast ports, big 2.080” diameter intake valves and a
highly efficient 64cc combustion chamber, the MOTOWN provides
significant power increases over other heads
on the market.
They are ideally suited for use on small block Chevy engines of 383”
or larger displacements.

Available bare or in complete assemblies, as well as in straight or
angle-plug configurations.
