Anyone using beehive valve springs on a slant-6?

I don't know abour beehives. Seems to me the slant really doesn't rev to warrant using that spring.
Thanks for the info - I'm familiar with those but am looking for actual gram weight counts - I appreciate your reply though. Engines don't have to rev high to benefit from a reduction of reciprocating weight - a modern Toyota Corolla employs the same ideology. It was a race-only tactic back in the day.... I'm just trying to apply modern tactics to an old mill. Thanks again!
