Customer Questions & Answers

    Answer: The Michigan Motorsports 1.550" Inconel exhaust valves are specifically designed to fit Cathedral Port LS Heads, including models 243, 799, 706, 862, 317, 241, 853, and 806. The dimensions and specifications of these valves ensure a perfect fit and optimal sealing, leading to better exhaust flow. This compatibility allows for seamless installation when upgrading or rebuilding your LS engine, maintaining its performance integrity.
  • Question: Are these valves compatible with all LS engine models?

    Answer: These Inconel exhaust valves are compatible with various LS engine models including LS1, LS2, LS6, LQ4, LQ9, LC9, LMG, and LM7. Each of these engines can benefit from the high-performance nature of Inconel valves. Whether you're building a race engine or enhancing a daily driver, these valves provide crucial improvements in heat resistance and flow efficiency, catering to diverse performance needs.
  • Question: What is the diameter of these exhaust valves, and how does it affect performance?

    Answer: These exhaust valves have a diameter of 1.550 inches. This size is optimal for ensuring an effective exhaust flow, which translates to improved engine performance, especially at high RPMs. A larger diameter can enhance exhaust scavenging, leading to better throttle response and increased horsepower. For performance enthusiasts, this means an overall boost in engine efficiency and power output.
  • Question: Can I use these valves for street applications?

    Answer: Yes, the Michigan Motorsports Inconel exhaust valves are suitable for both street and performance applications. Their durability and high-temperature performance make them ideal for daily drivers, providing resilience against wear. If your vehicle is modified for enhanced performance or if you are seeking reliability during intense driving conditions, these valves will effectively meet your needs.
  • Question: How do I properly install these exhaust valves?

    Answer: Proper installation of the Inconel exhaust valves requires careful attention to detail. Ensure that your cylinder heads are clean and free of debris, and verify that the valve seats are in good condition. Using appropriate valve springs and retainers is crucial for optimal function. It's recommended to follow professional guidelines or consult with a mechanic, particularly for performance builds, to ensure a perfect fit and function.
  • Question: Why should I choose Michigan Motorsports valves over others?

    Answer: Michigan Motorsports valves are engineered with high-quality Inconel material, ensuring exceptional strength and thermal resistance. They are specifically designed for Cathedral Port LS Heads, providing a perfect fit and reliable performance.

This can lead to increased power and torque, especially at higher RPMs. For enthusiasts looking to maximize their engine’s potential, these valves are a worthwhile investment.
  • Question: How do Inconel valves compare to stainless steel valves?

    Answer: Inconel valves outperform stainless steel valves in high-temperature environments typical in performance applications. They are more resistant to heat distortion and can maintain structural integrity under extreme conditions. While stainless steel may be sufficient for mild applications, Inconel is the preferred choice for high-performance builds, offering enhanced durability and longevity.
