Our custom 5 axis CNC machined new GM castings make these heads a must have for any performance oriented GM LS series engine. These heads provide up to a 65 cfm improvement over stock OEM versions. The 72cc chambers are great for lowering compression for applications where a power adder will be used. On a stock LS1, the compression will drop from 10-1 to approximately 9.0-1 with these heads. The Stage II bare heads feature our 5 angle 2.02”/1.57” valve job, hand blending, and custom honed bronze guides.
