QUALITY STRENGTH PERFORMANCE SINCE 1981
Dart 9° c-core heads offer the maximum performance
for cylinder head porters and machine
shops with CNC capability.
These are the ultimate castings for head porters.
The redesigned casting has been optimized for
CNC porting. Features include: raised intake
and exhaust port locations, optimized spark plug
locations, optimized deck thickness, expanded
water jacket capacity, bosses for down nozzles
and revised valve cover rail to clear long ratio
rocker geometry. Provisions for extra head bolts
have been added to each end, making for an
improved seal. Available in standard 4.400” or
4.500” spread bore spacing.
It is recommended that you contact a Dart technical
representative before placing an order
for this item. Detailed information about your
planned engine build will help to ensure that you
choose the right configuration for your motor
and that any special parts and considerations
are taken into account.
Heads are sold individually.
