Magnum 5.9 valve spring options

I'm looking for a cheaper option than the Hughes valve spring kit. I stumbled across these in an old thread here. Will these work on stock magnum heads with factory retainers?

Did you get anywhere with this? I am also looking for a cheaper option...aren't we all, lol.
In my search I saw MagnumMopar said he sold the same set for $50 less but, I don't believe he is doing business any longer
If it matters my cam is 220/230 @.05 496/513 112LSA
