The unique design of the inverted conical valve springs offers increased harmonic resistance for greater spring stability. This design requires less spring pressure for better valve control. Tests have shown more horsepower, higher RPMs, and longer life. This design is well known on GM Gen III (LS1/2/6) applications but is also great for other performance applications. Sets of 16. |
