COMP Cams beehive valve spring set lists top and bottom diameters of .959" and 1.061" with a 1.640" installed height and includes 32 springs. The beehive profile reduces mass near the retainer for improved valvetrain stability and higher RPM capability; these springs should be matched to appropriate retainers, seats and pockets for correct installed height and operation.
