Your photos do not seem to be of beehive springs. I know of no beehive springs that are dual springs. Your bottom photo appears to show a dual conical spring that is good for high RPM as indicated by the Al conrod.
My mistake they are dual conical but are tapered smaller at the top as can be seen in the pictures. They still need to clearance at the rocker. Difference is Beehive are rounded Conical are tapered.
If suggesting to penestar318 Beehive springs. Wouldn't money be better spent on rocker arms or modification to what he has. His springs are hitting due to 318 rockers being used with 340 diameter retainers . The factory just modified the 318 rockers by milling for clearance and they worked just fine on 340's.
