B/RB beehive valve springs

I have for sale an almost new set of beehive valve springs and 10 degree retainers that came from a B/RB set of heads. I don’t know the manufacturer but they measure 1.460” diameter at the base and 1.195” at the top. I measured the pressure and at an installed height of 1.830” they showed 145 pounds and with a lift of .450” they showed 276 pounds. Adding some shims will bring up these pressures if needed. These springs were used on the engine for dyno runs only and never saw any other run time. I would like to get $150 for all the springs and all of the retainers plus the shipping.
