What is the exact coil bind on these springs? The original post states "below 1.080", how much below?

What is the recommend duration/lift range for usage of these springs? Would they be overkill for something like 22x / below .600?

So, using a 1.800" install height with a max lift of .675" would put the safety margin at ONLY .045". That's under the .060" best practice.

If 1.080" is the CB height than .660" lift is max @ 1.800" installed height.

I just got my cam kit from you guys, & got PRCs. Are they the same springs you are discussing, only difference from the pics I see is mine have a chrome look? The ones in your pics do not.

Tell me more about this beehive spring... how will it compare to the PRC Platinum's I currently have and to the other high-quality beehive springs available? I'd like to switch to a single beehive so long as it won't affect reliability nor decrease performance.

There is no "recommended margin" of .060" You really have to know whats going on with your exact valvetrain. We have run .030" from bind static. Dont recommend doing that, but has been done.
