Beehives (Comp Cams) cost me a rebuild in '07. Engine/car were 2 years old and about 20k miles. Intake spring let loose and the valve broke off in the cylinder. Trashed the chamber and piston. Replaced with traditional dual springs.

The shop that did the rebuild blame the loss of two championships on beehives.

Comp Cams said that they had a supply of bad wire that may have been the cause of the failures.
