Speaking of Springs for Magnum Heads and Hyd cams.....

That sounds like it would be a solid option. I definitely don't know enough to say what will work or won't work. I'll be following this thread to see what comes of it. My plan was to just go snag some off of a GM 3100 currently but if there's a sub $100 option I would nix the 3100 springs and buy new.
