1.150 Valve Springs 16pk E-Street Heads

The 1.150 Valve Springs 16pk E-Street Heads from Edelbrock represent a purpose-built solution for small block engine builders and performance enthusiasts. Designed specifically for Edelbrock E-Street cylinder heads on small block Chevy and small block Ford applications, this 16-pack of valve springs delivers the reliability and precision needed for both street and moderate performance builds. These springs serve as direct replacements or upgrades, ensuring proper valve control across the RPM range.

Each spring features a 1.150-inch coil bind specification with a 1.250-inch outer diameter, engineered to work seamlessly with E-Street head geometry and valve train components. The single spring design incorporates a damper to reduce harmonic vibration and prevent surging at high RPM, critical for maintaining consistent valve seating and avoiding float conditions. The Sure Seat design ensures positive seating pressure, promoting durability and predictable performance. This engineering approach balances spring rate with stability, making these springs suitable for street performance where reliability matters as much as power delivery.

Engine builders restoring Edelbrock E-Street equipped small block Chevy or Ford engines will find this 16-pack essential for complete valve train refreshes or upgrades. The set provides springs for all intake and exhaust positions on a typical small block configuration. Installation requires proper seat and spring height setup during cylinder head assembly to achieve rated preload and coil bind clearance. For those seeking improved valve control, better high-RPM stability, or replacement springs for worn units, this Edelbrock offering delivers proven performance at a competitive price point.
