Tappet shim replacement 08 DF150's

I don't expect that you will find that you need to make any adjustments at 220 hrs. I checked mine on my pair of DF140's last fall, 500 hrs on each engine, all valves were within specifications and this was the first time that they were checked.I was able to reuse the valve cover gaskets.

On the other hand, my '07 DF150 had some WAY out. and most were out in the bad direction, They were way too tight. Of the 16 valves, only 5 were in spec.

need to get two things a full service engine repair manual and a tool and a feeler gauge
measuring the clearances is the easy part!

the above link has a couple of pictures of a tool I made

How hard is it to check or replace the shims? Is it worth doing it yourself . looks like you would pay many $ to get it done at a dealership on two motors .
Can you get a set of the shims in various thicknesses? did not see a set on the parts diagram, single shims are $ 8.43
Looks it would take forever to take the valve covers off ,measure 32 gaps on the tappets of two motors ,order the right shims then install . Any advice is appreciated. 220 hours on the motors.
Thanks.
