HEI distributor tuning problem

I switched to a HEI dist. About a month or so ago and I can't seem to tune out the tapping at the 50-55ish speed. I have played with different base timing settings. I have tried a different vacuum advance module? and even went to the heaviest springs in the distributor.
I'm thinking maybe the distributor is just bad?
The motor (350) does have some kind of performance cam in it, maybe that's effecting it? (Vacuum)

Any thoughts?

Thanks!
Joe
