Four basic ways I can think of, most spendy to cheapest:
Test indicator
Depth gauge
Caliper
Lay something flat across the piston and measure the gap
between it and the block, with stacked feeler gauges.

If you get to the right person you can do head work fairly
cheaply. :-) Guides are easy to remove and replace yourself
with nothing more than a hammer and a drift. Use the right
drift and you usually don't even need the correct reamer, which is
still cheap. Toughest part is the vavle compressor tool. I made one
that works well with the cast, NA intake to lever against. Otherwise
I'm able to borrow a "correct" one. It's not too spendy to have the
intakes and all the seats ground. Then you have to shorten stems
to get back to the right shim range.
I was able to give a hand at a local machine shop one day and he
said if I did that, I could use the valve grinder in exchange. It was just
some help moving a couple things and.... grinding some valves for a
customer while he balanced a crank or such. Now a shop up the
street has an old valve grinder and I get to use it for "beer money" to
grind my valves, seats and shorten stems squarely. I've done it with
a regular bench grinder too. You gotta work the system! :-)

Owner's manual actually tells the "correct" interval of either
15K or 30 K miles. Seems like I probably go about 20 ish as
I do a lot of short runs. Wife just came home from KS or she
could've been some help. Been a while but she's seen me set
timing and valves a few times. :-) (Like she'd have had time for
a house call... or would've wanted to admit she knows anything
about cars either!)
