Here is a example:
Product Catalog - TAPPET HOLD DOWN TOOL TAPPET HOLD DOWN TOOL 303-540
I think I have the same tool, its just a long time ago I used it, and then only 1 bucket at a time.

The bigger question is:
Where do we get the shims?!
When I raced an eight valve Fiat back in the 80's, I had a complete shim set in stock so I could do the whole adjustment in one sitting.
With 32(!) shims now, and them being "Jaguar" shims, I can't imagine what the cost of a similar set might be. Which means I would have to remove, measure and re-install all the shims; then go to the Jag dealer to either buy or place on order the ones I needed; then go at the engine AGAIN to install them.
Sheesh....

I would suggest that you use the tool for the intake cams and remove/install the exhaust cam to replace tappet shims.
You can remove the intake cam also but the front cover needs to come off. (alot more work)
It is easier/faster to remove the exhaust cam than to use the tool. (it is tedious)
After you swap a few shims on the intake cam you will see what I mean, take my advise and just pull the exhaust cam after measuring.
The shims can be ordered from the Jaguar dealer but they are a little 'pricey'.
I never priced them from a Ford dealer.

You are CORRECT SIR!!!!!
I usually spray some solvent to lower the oil viscosity between the shim/tappet and blow compressed air in the edge to ATTEMPT to dislodge the shim.
A strong magnet might help also and it will work fine if the cam is removed.
