1/16" is .0625", and I'm unhappy with a .005" difference in lift from one valve to another. I don't know if that would cause the problem you're having, but before considering a cam change, I'd want to run some very accurate measurements with as little variation as possible. Am I correct in hearing you're running Rhoades lifters on a street-driven 327? WHY? Those things are supposed to be used to make an extremely radical cam more able to be driven on the street. If you're running a cam that needs those lifters, you're WAAAAAAY over-cammed, and the engine is going to run lousy anywhere except wide-open throttle.
