Howards Cams Ovate Inverted Conical Valve Springs
Howards Cams Ovate inverted conical valve springs offer increased harmonic resistance for greater spring stability. They require less spring pressure for better valve control. This design is well known for GM Gen III, LS1, LS2, and LS6 applications but will also work for other applications. They're performance replacements featuring precision winding, heat-treating, and finishing processes. These springs are designed for stock-style retainers.
