Be sure to do a very thorough check on the condition of the cam lobes with a degree wheel and a dial indicator- - - - -if the lifters are showing any measurable amount of wear, the cam lobes will be worn also. Schneider Cams in San Diego regrinds stovebolt cams, but a Melling CCS-1 cam is a really good option if you decide to go with a new cam. It's slightly better than the 261 engine cam that was also used in the 6 cylinder Corvette, without a creating a lumpy idle and bad intake manifold vacuum.
