I tried this method today on my 86 300SDL and it worked with a little extra effort.
My ALDA would not come off with channel locks - it took a few smacks with a 12" extension and a hammer on the side of the ALDA to get it loosened.
The real problem I ran into was the rear bolt ( I used the plastic shut off valve).
There is virtually no clearance for a 10mm socket to get on that rear bolt once the bolt gets level with or below the plastic body of the shutoff valve.
I had to remove the front bolt to move the shutoff around and get the socket on the rear bolt - barely able to get the socket on.
Once I got the socket on - of course then you have to deal with getting the ratchet on the socket.
I read some where that the later version had Torx bolts - this might have been easier if they had a smaller head than the 10mm bolt.
Overall - a lot better than pulling the intake off though.
