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.

They’re great out of the box in “as cast” form. With 235cc intake runners they’ll provide ample flow to keep up
with the camshaft/intake combinations of most larger displacement small block Chevy engines.
For those who desire optimum performance, World Products offers these heads CNC-ported.

With 250cc intake runners and enlarged, 90cc exhaust ports. The CNC ported heads also boast a larger 2.100”
Manley stainless steel intake valves, so you can readily see the kind of power these designs (developed by
Kuntz & Company) will deliver.
