Cylinder Head Packages
Our 5-axis Rottler CNC and Newen Contour seat and guide machines are the most advanced on the market today. This allows us to produce ported heads of exceptional quality and performance. How do we know? Because we use them ourselves!
The LS heads normally in stock are GM LS3 (seasoned), AFR LS, All Pro LS, Dart LS and Dart BBC. The aftermarket heads come in as raw porter castings into which we machine our desired combustion chamber and port. The LS heads can be finsiged to either LS3 or LS7 ports. We have a wide array of valve and spring types to choose from. Call us at 815-725-2727 to get the perfect set of heads for your needs.
