With the Beehive springs and steel retainers, the engine pulled to 6300 RPM with no other changes.

To date, I can only remember ever seeing one broken Beehive spring, and I believe it was the victim of other parts failures, not the spring itself.

Paul, Does that mean one wouldn't have to spend the extra money on a tit retainer then if using the beehives? I meant 1.800 IH since it coil binds at 1.100 in my post above. I think I will run some tool steel retainers, there lighter than the moly ones and only a little heavier than tit and half the price!
