Another small block chevy cam question?Modern VS old school cams...?

OK I'm building a mild 383, s/r heads, 9.5:1 comp, rpm intake 750 carb, headers etc going in a 75 shortbox with a TH350 and 2200 stall. I almost have a cam picked out something with under 490 lift and 230 dur @50. I was going to but something like an old school crane, comp, elgin or isky 480 single pattern cam but I've been told to run a "modern " cam like a Comp XE or Lunati voodoo or Crane Z cam. Will these modern tech cams really run circles around the older stuff? Are they worth the extra $70 or are they just new hype for the cam companies to sell cams? My biggest concern is with all this increased "area under the curve" and faster ramps, doesn't this lead to valvetrain harshness and increased load and accelerated valvetrain wear? I am concerned with longevity with these grinds. What I want out of a cam is a noticeable lope at idle and good power and torque up to 5500-5800 rpm. I would like to hear the pros and cons of these modern cams. Thanks, Tim.
