I believe it was Rayler who was finding this out first hand. Also when gathering parts for my project, the tech at PAC advised against going with the beehives in my application. It is easy to see that a beehive would have some inherent advantages or they wouldn't be so prolific in the OEM performance applications, but maybe for higher lift, BBC applications they may not be the best. Any comments?

Maybe that's their limit on lift? even though I'm not running the highest rate ones... Although the LS motor guys (cars) are running crazy high lift numbers with them I thought?
