My thinking (and I've been wrong. sigh, a lot) is this:
The valve to piston clearance is a function of the cam lift and cam timing. Without the cam timing set I don't have a good way to check it.
(The closest the valves get to touching the piston isn't at TDC.)

The VtoP clearance check I'm talking about is the turn-the-adjuster-screw-and- count-the-turns method.

I'm just tired and a little dense right now so cut me some slack if I'm not "getting it".
