Can not find Phantom Knock cure

[Kapok6]

Alright, I have been battling PK (Phantom Knock) for over year now. I have put it the revised lifters, new knock sensor, then I took it out and filled in the knock sensor w/ JB weld as recommended on this site, and I know for a fact I am running rich. Are there any other ideas out there as to what could be causing this because I am at my witts end. The engine has 86K original miles and compression is 150 across the board. Thx in advance for the help.

I will check timing marks again, but they we set properly when I replaced the timing belt. I don't have bet valves or anything yet. Compression is 150 across the board. I will look into it further though, Thx.
