different valve spring options

so i have this cam i want to put in my 360... is there another spring i can run other than the comp double springs(995-16).. i already have new seals and would want to have to buy Viton seals just to run the double springs... cam is comp CL20-224-4.

What installed height are you at now?
You might want to know that first.
If its decent, like 1.75 or better you could run a set of +.050 locks and choose from a better/greater selection of springs in the 1.80 arena.
Too little spring is a killer of power and parts. More common than people think.

I'd check the height 1st.
