I am looking for suggestions.

Manley Next Tek?

Isky Tool RRoom?

Isky PSI?

Cam specs at .050 are:

Int open 30 btdc close 74 abdc 284 duration .809 lift

exh open 83 bbdc close 39 atdc 302 duration .782 lift

Lobe separation 112

Thanks for the help.

Your best bet is to use the springs that are recommended by the manufacturer of your cam.

I've had really good service from the Manley NexTek springs that were ordered factory installed (roller spring option) on a brand new set of BBC AFR heads.
Two years old now...running .763" gross lift on the street.

Manley Nextek would be my choice for this

Comp also has some excellent stuff

I can get either those or Isky whatever you wish ;)

email me if I can help.
