Street Fighter Head

This is the first step in increasing the horsepower and torque for sportster customers while maintaining use of their existing stock components. This head can be used with reversed dome pistons to increase the displacement to a 1200 while maintaining your existing cams and pushrods. A very nice fit for the first step in a performance upgrade. When using the reverse dome pistons you gain a .500 of bore size per cylinder making this a substantial increase in power. Check the specifications table for details on compatibility with your existing components. For more details on the best fit for your build – call T-Man Performance.
