Is this bad? (440 Six Pack)

I think I had something simular to that as well in my engine. I didn't think anything too much about it at the time because I thought it might normal;ly be like that. or maybe it was some weird mod you can do for something. Anyways if you would like me to pull my distributer I will check it. Its in my 440 duster. Kinda the same thing...fresh rebuild...never installed or started till I put it in.
