The XE and voodoo line are both modern aggressive lobe camshafts but I hate comp so my choice is the voodoo. I wouldnt worry about the lift and floating the valves. You "should" change springs to match but its such a mild camshaft that you can get away with stockers if they have low miles. I once ran a Isky 280 Mega in a 20yr old 327 and used the stock springs and valve flaot wasnt a problem. If you plan a spring change then the Z28 replacement springs will be more than enough and you should be able to get springs and valve seals for less than $100.
