As far as I know it can't be done as the plug hole is at an angle and the piston will jam the dial plunger, I've tried. You can only use a dial gauge on the head if it's a centre plug one

Agree with Wack the probe on the dial gauge will slide and give false and varied readings. You could make your own by taking the centre out a spark plug and fitting a bolt through. You can then adjust it to the correct length but you need to grind the end so there are no sharp edges.
