Can't be the cam, it has to be me?

Sure can be that far off.
We can't check your technique without knowing a few things. These are probably dumb question and not meant to insult you.
- Using a degree wheel? Yes? Degrees CW from the 0 on the degree wheel are BTDC, and CCW from the 0 are ATDC.
- Are you measuring at .050" TAPPET lift? Not at .050" valve lift right? (But that would not show up both intake events off in the same direction....)
- If you needed to advance the cam, then yes, use the 8* advance marked slot. Your last question is perplexing....
