[Vwdiesel] Swapping a good head-DIY head prep

[Will Taygan]

How should stem length be set?  Is there a measurement I can take with
my current rebuild, or is it a bit of eyballing (valve with outline on
piston gets ground kinda thing)?

Does using a thinner shim helps "shorten" the stem, or does it just
change the time the valve is open?

Thanks,

Will in Alaska.
