My rapid motorsports cam came with non behive dual valve springs and retainers. Im curious to see how they hold up with street driving. My lift is just over .600. The only concern I have with beehives around .600 lift are they still a good idea. And what is the limit on beehives. Eric L

Going from memory, but it seems like I remember seeing a chart showing that the .651 family of cams from Lunati are very big under the curve. There is a page hiding somewhere here on Ls1Tech that shows the .200 numbers and the Lunati lobes are slightly bigger under the curve than the Comp LSL/LSR lobes, which are quite aggressive also.
Here are some of the other Lunati grinds..

So there cams for carbs or for cathedral heads? no options for rectangular heads?

nah, reckon the last two sections are for rectangular port. i thought the valves just just squeeze in the 3.9 bore, the issue being flycuts hit the side of piston and make a weak point. correct me if i'm wrong.
or as you say run a sleeved ls1 or ls2 block.

off topic, my pistons are mahle power packs that are set up for ls2s, but had to widen the valve reliefs for the big cam.
