I'd check to see if the old vortec sorings will manage the .504" lift without going into coil bind, and use them for the break-in period if they will work. Give the cam every advantage you can during break-in.
Naw, I'm pretty sure the max is .470 on them.... seems like even more risk honestly than using my regular springs
