I'm almost 100% sure I posted the wrong number for the valve springs. I just have stock 5.9 stuff, my motor is original. I just wanted to track down all that info to kill time. Anyway if I remember correctly I think the stock valve springs are good for .515" of lift, so that cam with a stock valvetrain shouldn't be an issue... I am no expert by any means, and I hope you get this thing figured out.
