<strong>Dart</strong>'s 11° Little Chief CNC is the ultimate<br />
small block cylinder head. Designed with Pro<br />
Stock style oval ports, big block style canted<br />
valves and “semi-hemi” style combustion<br />
chambers, the Little Chief is a radical departure<br />
from traditional small block heads.<br />
The huge flow resulting from the 11° valve<br />
angle and splayed valve layout combined<br />
with spread oval intake ports, raised runners<br />
and highly efficient combustion chambers<br />
deliver amazing power!<br />
It is recommended that you contact a <strong>Dart</strong><br />
