Valve springs for howards cams

Howards recommended Spring kit #98113-K12 Beehive 108#@1.800 329#@1.265
Edelbrock 8525 128# and 339#
Howards catalog for the cam I'm looking at is dual spring 122# seat and 353#open
By the way cam is Howards 711451_08 506/506 lift

The ones on the heads now are eddy 5767 105# seat and 320#
They actually look closer than the behive spec from howards
I am trying to do this with no machining.
