Howards Cams Beehive (Inverted Conical) Valve Springs
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 rpm’s and longer life expectancy. This design is well known on GM Gen III (LS1/2/6) applications but is also great for other applications including Chevrolet small blocks, Chrysler 5.7L Hemi, and many other performance applications.
