Gwatney Performance
  • Many hours of R&D have gone into the development of our incredible Gen 5 LT2 CNC program. With huge flow numbers and an efficient port shape, the GPI CNC ported Gen 5 LT2 offering is truly bolt-on performance!
  • Our LT2 head was developed specifically for the stock displacement LT2 engine to deliver improved cylinder fill in the lower RPM ranges while adding substantial airflow increase in the upper Ranges as well.
  • Optimized Airflow Design: Specifically engineered to boost airflow while preserving port velocity, ensuring a harmonious balance for remarkable efficiency.
  • Refined Intake and Exhaust Ports: Meticulous enhancements to the intake bowl and seat area, coupled with improvements to the exhaust port, contribute to superior engine performance.
  • Unaltered Power Curve: These heads are designed to elevate engine output without shifting the existing power curve, maintaining the engine’s characteristic responsiveness.
  • Intentional Machining Choices: A close visual inspection reveals selective machining – certain areas of the intake runner remain untouched, and the hump beneath the rocker bolt is preserved. These deliberate choices are tailored for the C8 street application.
  • Proven Performance Results: The effectiveness of these heads is evident in their performance, making them a standout choice for C8 applications where results are paramount.
