Is your camshaft some kinda secret? It'll help tremendously if we know the specs. Help us help you.
Sorry should have thought to post cam specs.

Hughes gets there springs from PAC.
Search elsewhere for your be sake spring.
Check specs on the spring and match it up.

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

Didnt comp make a drop in?
Hughes?

Otherwise cut the pocket for a more common spring.
130/300 sounds like enough to me. Jmo

Yes, I believe that Comp is making the Hughes package.
I am also considering the Pac 1286-16's

Sorry, I just re read my post...I was referring to the Hughes set when I said MagnumMopar mentioned selling the same kit for 50 dollars less...I wish he was around to at least relay the info on where to get them if not get them from him.

MagnumMopar's departure from the scene was a big big hit to those of us running factory Magnum EFI in our cars. So much knowledge, so many good product offerings, all vanished.

EDIT: I just thought to look him up and I see he's been posting again, it's good to see he's back.
