Edelbrock 61775 RPM head valve springs

This is a 408 build. I'd like to know if the valve springs on these heads are good to go on this build, plans are for 9.5 or 10.5 CR and a Lunati camshaft with either .560/.565 or .535/.550 gross lift. I have them at the shop now being looked over.
The only other set of springs I have are MP #848 silver springs rated at .550
Edelbrock specs say theirs are good to .580
This is a Magnum block, a roller motor.
