I just had the heads rebuilt on my 427. It had a mild aftermarket cam, forget the specs. I have the spring specs written down somewhere. They only have about 500 miles on them. Had some leak down in one cylinder, which snowballed into a huge full rebuild, with a roller cam. If the springs suit your needs, I will ship them to you and you can have them! I do know that they are stiffer than stock and a quality aftermarket spring. I'll look for the info and send it your way, if you're interested?
