MacDaddy Racing offers many different porting styles for riders looking to gain more horsepower and torque. In all Dyno testing I see a minimum of a 10% gain in power from my head porting. In most cases expect to get your head sent back to you fully ported in three weeks or less. Send heads to below address with your contact info inside, also what type of riding you do, what pipe your running, what fuel your using, and the year, make, and model of your bike or fourwheeler.
