In various tests performed by gmhighperformance.com, the Livernois Stage 3 CNC Ported heads outflow was over 30cfm more than SLP L92’s at .600 lift on intake and 15cfm more on exhaust…
The heads have been milled .030 which bumps the compression up by about .5:1 which still allowed me to run street gas while also picking up some seat of the pants torque and hp.
They have about 30,000 miles on them.
