Are these valves about done ?

Just got done checking my valves on my Griso 1200 8V that now has 100k miles on it.

During the first 50k miles I kept checking the valves at the specified interval; 6,250 miles.
And I felt there was so little adjustment needed; that after 50k I decided to switch to checking valves every 10k miles.
At 60k, 70, and 80k. There was still very little adjustment needed.
So I didn't check at 90k. And instead waited until 100k.
At which point; every valve needed a little more tightening. But not a huge amount.

I recall thinking to myself at 80k. That the adjustment screws are getting rather close to the lock nuts.
I thought when new; the adjustment screws were about 1/8 inch above the nuts.
And was starting to think that maybe during all the previous adjustments I was over over tightening them.
Well during this adjustment at 100k. I decided to prove this theory.
So I took photos of the screws and lock nuts. And compared them to Pete's photos in this thread:

Here are my photos:

Do most of the adjustment screws on my Griso look like they're about done ?

Thanks;

If you have to screw in the adjusters, it is the valve actuating parts that are worn, not valve seat recession. So take a look at the cam followers and such.

Thanks !
So I take I'm not imagining things. And those screws are a lot farther into the nuts.
