These heads deliver maximum horsepower and torque in high performance street and light duty racing applications. Full CNC porting of the combustion chambers, intake & exhaust runners; improving air-flow & overall performance potential. These heads have a 24.5° x 4.4° intake valve angle, 15.5° x 4.2° exhaust valve angle and exhaust ports that have been raised 0.125 but are still in the stock location. Spark plug angles have been modified to produce a smooth flame front for increased fuel efficiency & maximum power. Two combustion chamber sizes are offered, 110cc and 118cc.
