June 29, 2009 – Nacogdoches, TX–Now you can make your new crate engine or Corvette really hot with a pair of LS7 Mast Black Label CNC cylinder heads. These 12-degree bad boys fit ANY GM Gen IV LS engine or 6-bolt LSX GM, World Product, or RHS Block with a 4.125” bore or larger and work great with extreme performance camshafts (available separately from Mast). In addition, rocker stands are available for factory LS7, Jesel roller, T&D, or Mast rocker arms. The factory LS7 intake manifold will bolt on with no modifications required.
The heads feature stainless 2.200” intake and 1.600” exhaust valves. At .700 lift, these amazing new heads flow 395 CFM on the intake with a 274cc port volume and 249 CFM on the exhaust with an 87mm port volume on a Superflow Flow Bench with a 4.125” bore plate. These cylinder heads are an excellent foundation for power with a great combination of port velocity and flow. Simply put, Mast Black Label CNC LS7 heads outperform ANY available LS7 cylinder head on the market.
