120R-124 KIT

This 120R-124 kit upgrades the fully CNC ported head from Harley-Davidson. We install oversized, high flow valves and enlarge the inlet to 1.800, increasing the flow and velocity of the head. Your stock 120” cylinders are bored to 4.125” making your motor a 124”. Pair this with one of our cams and our custom 20° angle pistons to get the most out of your performance motor. Cam selection is based on your desired performance and riding style needs.
