Specs on Heads Per Patriot Performance.
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 heads feature 21-4N 2.02”/1.57” stainless steel valves, our Original Patriot Gold Dual .650” Lift springs, titanium retainers, Super 7 machined locks, custom honed bronze guides, machined spring bases, and viton rubber seals.
