They are wiped out. Matt was right, you really should use a micrometer... much more accurate. Best is to measure multiple points on stem and guide and write down numbers. Take smallest stem and largest guide measure and the difference is the clearance... yours is .006 which is .1524 mm plus the inaccuracy of the dial caliper (they are limited in precision by a minimum of .01 mm) gives you .1724 total clearance. factory calls for .057 largest new intake and .077 largest new exhaust. This is kinda big already. Service replace limit is .15 Intake and .2 exhaust but that kind of wear would probably kill the valves before it got that large.

Get new valves and guides. Your engine will thank you. Also have the seats done while in there for better sealing and when returned from shop lap them in lightly.
