There is a very good chance you will have an issue with valve springs/retainers. The stock vortec head is not made to handle that lift. I seen specs stating .460 to .480 max lift. Crane makes a kit,10309-1, with springs and retainers that allow up to .550 lift. these are drop in without any machining. Also keep in mind you need a new intake, self-aligning rockers, and center bolt valve covers.
The RPM range starts out at 1500. I don't think a higher stall converter will be necessary but maybe recommended. It looks like the cam is pushing the envelope. Your best friend(s) may be the support people at Lunati. Too 'big' of a cam for a street car may sound nice as it idles but may be a pain especially if running 3.08 gears.
