A great way to bolt on some easy horsepower and torque is with our billet head. Our improved combustion chamber is designed to run on 91-93 octane premium pump gas. The compression ratio is increased and the squishband has been changed to increase the squish velocity. It's a very noticeable gain, and on a stock machine no fuel controller is needed. We have them for both the M8000 and M6000 models. For best results we suggest increasing the weights by about 2-3 grams when you install the head. Or we do have our clutch kits for those models as well.
