LS7 CNC Ported Cylinder Heads

The Gwatney Performance GPI-LS7 Heads are a performance-oriented cylinder head package that begins with the meticulous disassembly of OEM LS7 cylinder heads. Each head is then thoroughly bead-blasted and cleaned, with any rough edges deburred to ensure a precise finish. Central to this package is GPI's in-house CNC porting process, utilizing a hand-developed port program. The result is a significant increase in horsepower while crucially maintaining a strong torque curve for a well-rounded performance increase. The heads are built with a focus on maintaining exact tolerances. While OEM LS7 Titanium Intake Valves are inspected, replacement options are available if needed. For exhaust valves, customers can choose from options provided by Ferrea, tailored for either naturally aspirated (NA) or forced induction builds. Various valve spring options are offered to suit different performance requirements, ensuring compatibility with a range of setups. This comprehensive cylinder head package includes the reassembly of the cylinder heads and return shipping, offering a complete solution for enthusiasts looking to upgrade their LS7 engine.
