Not to beat a dead horse here Fen, but figure # 9 under step # 21 shows the TDC notch at the 3 O'clock position (Cylinder #2 at TDC position), you said you did yours at BDC, because the above did not work for you.
I must be missing something, but I don't know what it is. I tried it both ways at TDC and at BDC with the same results. I think I agree with you about the LH Cam being the issue. I'll follow the steps in my previous reply this evening
Thanks again
