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

Before I did as Yellow Rose posted, I checked the ICL with the cam as it was (degrees @ .020 before and after max lobe lift, difference divided by 2, I was assuming the nose is the same radius on both sides). Got 113.5 degrees ATDC. Followed his directions, ended up with the chain fitting at the 8 degree keyway. ICL is now at 106, but I'll put my piston stop plate back on and verify TDC one more time. Am I still correct in thinking this cam is 8 degrees off?
