How to Choose the Best Automotive Replacement Engine Valve Springs
Understanding Valve Spring Design and Configuration
The architecture of a valve spring significantly influences its performance and suitability for various engine applications. Single valve springs, like the COMP Cams 980-16, are typically found in factory applications and mild performance builds. They are generally simpler and more cost-effective. Dual valve springs, such as the COMP Cams 995-16, incorporate an inner and outer spring, providing increased stability and resistance to valve float at higher RPMs. This design offers a safety net, as the engine can still operate if one spring fails. Beehive valve springs, exemplified by the BTR "LS6" BEEHIVE VALVE SPRING SET, feature a tapered design where the top coil is smaller than the bottom. This reduces mass at the retainer, enhancing valve train stability and allowing for higher lift capacities while often requiring less spring pressure for a given application compared to traditional straight springs.
Evaluating Pressure Ratings and Lift Capacity
Critical to valve spring selection are the seat pressure, open pressure, and maximum lift capacity. Seat pressure, as seen with the Edelbrock 5767 (105 lbs) or COMP Cams 995-16 (115 lbs @ 1.700 inch), determines the force holding the valve closed when the engine is at rest or the valve is on its seat. Open pressure, such as the 336 lbs @ 1.150 inch for the COMP Cams 995-16, indicates the force exerted when the valve is fully open, which is crucial for preventing valve float at high RPMs. The maximum lift capacity, for instance, the .560" lift rating of the BTR LS6 springs, specifies the maximum valve lift the spring can safely accommodate without experiencing coil bind or excessive stress. Mismatched lift capacity with a camshaft can lead to severe engine damage, indicating the importance of precise selection.
Application Specificity and Compatibility
Choosing valve springs tailored to your engine's specific make, model, and modification level is paramount. Products like the GM Genuine Parts 12706568 are designed as direct OEM replacements, rigorously tested to General Motors' standards for specific Chevrolet, Buick, GMC, or Cadillac vehicles. These are ideal for restoring factory performance and reliability. In contrast, performance-oriented springs, such as those from BTR Brian Tooley Racing, are often engineered for specific engine families like the GM LS platform, offering upgrades for increased power and higher RPM capabilities. Similarly, COMP Cams offers a range of springs designed for various engine types, including specific beehive options for Ford Modular engines. Ensuring the spring's outside and inside diameters (e.g., Edelbrock 5767's 1.460" O.D. and 1.060" I.D.) match the cylinder head's spring pockets and retainers is also crucial for proper fitment and function.

Common Mistakes to Avoid
Overlooking Correct Seat and Open Pressure Ratings
A common mistake involves selecting valve springs without adequately matching their seat and open pressure ratings to the engine's camshaft and intended RPM range. For instance, using a spring with a lower seat pressure like the COMP Cams 980-16 (92 lbs @ 1.700 inch) in an application that demands higher stability, such as one requiring the COMP Cams 995-16 (115 lbs @ 1.700 inch), can result in valve float. This leads to power loss, reduced engine efficiency, and potential damage at higher engine speeds.
Ignoring Maximum Lift Capacity Requirements
Many users fail to consider the maximum lift capacity of the valve spring in relation to their camshaft's lift. Installing a spring that cannot accommodate the full lift of the camshaft, such as using a general-purpose spring with a high-lift cam designed for the BTR "LS6" BEEHIVE VALVE SPRING SET (.560" lift), will cause coil bind. Coil bind occurs when the spring is compressed to the point where its coils touch, leading to immediate and catastrophic failure of the spring, valve, and potentially other engine components.
Mismatched Application Specificity and Design
Another frequent error is assuming that all valve springs are interchangeable or that OEM parts are sufficient for modified engines. For example, while GM Genuine Parts 12706568 are engineered to rigorous standards for factory GM vehicles, they are not designed for the increased demands of a performance camshaft or forced induction setup. Similarly, attempting to use a generic spring when an application-specific beehive design (like the BTR LS6 springs for GM LS engines) would offer superior performance and longevity demonstrates a lack of understanding regarding modern valve train requirements.
