Don't know how either relate to TDC, but I have always used the rule of
nine - adjust No. 1 valve when No. 8 is down, No. 2 when No. 7 is down etc.
As these two are down at different times they can't both be at TDC. I
believe the principle is to adjust a valve when its lobe is on the opposite
side of the camshaft from the follower.
