Melling LS Valvetrain Kit Focused On Measured Performance

Melling Performance continues to strengthen its LS engine offerings with the release of the Melling LS valvetrain kit, part number MVK100. Rather than chasing broad, vehicle-specific fitment claims, this kit is built around clearly defined component specifications, making it a strong option for experienced engine builders who select valvetrain parts based on measurements, spring pressures, and installed heights.

A Complete Melling LS Valvetrain Kit Solution

The Melling LS valvetrain kit combines all critical components needed for a matched upper valvetrain assembly. The package includes stainless steel intake and exhaust valves, valve springs, chromoly steel retainers, valve locks, and valve stem seals. By supplying these components together, Melling eliminates the guesswork that often accompanies mixing parts from multiple manufacturers.

This approach is especially valuable for LS builds where camshaft profiles, cylinder head modifications, or custom combinations demand known spring loads and valve dimensions. The Melling LS valvetrain kit is sold strictly by specification, giving builders the flexibility to confirm compatibility with their specific setup.

Valve Spring And Valve Specifications

At the center of the MVK100 kit are the 466594 valve springs. These springs provide 151 pounds of seat pressure at a 1.800-inch installed height and 417 pounds of open pressure at 1.150 inches. A solid height of 1.064 inches allows room for performance-oriented lift while maintaining stable valve control at elevated RPM.

The stainless steel intake valves feature a 2.007-inch head diameter with a 45-degree seat angle, while the exhaust valves measure 1.602 inches at the head with a 45.15-degree seat angle. Both valves use single lock grooves and are paired with chromoly steel retainers and matching locks to complete the system.

Built For Builders Who Work By Numbers

Melling makes it clear that this kit is intended for knowledgeable builders, not as a universal drop-in solution. It is designed for those who already understand their camshaft requirements, installed heights, and spring pressures, whether for a street performance engine or a more aggressive combination.

With the MVK100, Melling Performance reinforces its reputation for producing precision engine components. For LS builders who rely on hard data rather than guesswork, the Melling LS valvetrain kit delivers a clean, well-matched solution backed by detailed specifications.
