Joshua, the L82 motor was a 350 using flat-top pistons and 76 cc heads for a compression ratio of 9.0:1 and made 245 hp. The cam was GM part number 3896962 with a lift of 0.450 / 0.460. It should work well on the street if your compression ratio is around 9.0:1. It should also work with stock-type valve springs.
