Lingenfelter CNC Ported Aluminum Cylinder Head C6 Corvette LS2 2005-07, GTO, C5/Z06, Cadillac CTS-V

Product Details
Lingenfelter offers a CNC ported version of the 243 casting aluminum cylinder head used on the 2001 - 2004 Corvette ZO6, Cadillac CTS-V and the 2005-2007 LS2 powered C6 Corvette, 2005-2006 GTO & SSR
The port and chambers are carefully designed to provide the best combination of high flow capabilities and improved port velocity. This combination provides excellent horsepower gains while maintaining a strong torque curve. Lingenfelter 243 casting LS6, LS2 cylinder heads are precision CNC machined in house to insure that exact tolerances are maintained.
The Lingenfelter CNC porting procedure is a computer controlled machining operation that duplicates exact details from a finished Lingenfelter hand ported cylinder head. Hand porting is a very labor intensive and time-consuming procedure that takes years to perfect. By CNC porting the cylinder heads the high cost of hand porting is reduced, plus the CNC porting is more consistent and will produce better results. Each CNC ported cylinder head will have the exact same port and chamber configuration as the original master used to develop the CNC program.
Following porting each head receives:
Precision 3 angle valve job to maximize flow & provide extended life
CC checking chamber size for correct compression Surfacing to insure deck flatness
Professional assembly, setting spring height & checking all tolerances
Base price package includes porting your supplied cylinder heads. Upgraded valves and springs are additional cost.
