What you have and where the knock is (assuming light load low rpm tip in).... If it knocks wide open, you may be after more than a cam on your next parts order. 
Every one is trying to help you get it humming, don't take the advice as insults.... A lot of experience to draw from here.

Yes, a little less advance and it will spark knock less. I wanted it advanced to get the whole big cam experience.
The tick is lifters. If it's something else then I will be fixing something else some day, of course, doesn't that go without saying?
Looking back, the only comments that really helped at all mostly came from Clay.
Not saying that others weren't trying to help, their comments didn't help. Mostly condescending.
You helped me make sure my pushrods were the right length, thanks.
There's a lot of 'noise' around here that's not very positive. Sorry folks are not happy. Glad I have a life that keeps me positive and moving forward.
