I had to re-shim mine when I fitted a new head.
Checking them is fairly easy. Changing them is a faff as you have to measure the clearance, if it's out, you have to remove the old shim and get a new one that makes up the difference. I found very few people had them in stock so I had to order them on the internet and wait a few days for them to arrive with the head off my bike. Not great if your paying for workshop space or need your bike everyday.
