Our Billet Head for the Polaris 850 Patriot is an easy way to bolt on some easy power. We have changed the combustion chamber design to produce a quicker revving motor. It will also increase the peak horsepower. Interchangeable domes are available for higher elevations or race gas. This head work really well on ported motors as well.
