How finicky are the tolerances on the quick release plate on the Kirk collar?  Will it work with any A-S compatible quick release ball head?

just make sure you have the screw type clamp on your ballhead as opposed to the lever release QR clamps if you are mixing brands of arca swiss plates as the screw clamps can be tightened on most of them whereas the lever release clamps may have slightly different tolerances specific to their proprietary plates and may not clamp tight to others.

You worded it the way that I should have!  Yes, that's my concern.  Want to use a lever-type quick release, and aware that they can be finicky.

Looking at the Acratech ball heads, and know that Wimberly plates will work them.  So will the Kirk collar fit in the lever-type Acratech ball head?  And from Denis mentioned, the collar could be screwed to a QR plate, then set on the ball head.

Worst case scenario, send the head back & exchange it for one that works.

From what I have read, Wimberley and RRS plates have same tolerances and will work in lever release clamps from each other. I believe RRS lever clamps will not tightly hold plates from Kirk or Markins. Kirk, Markins, and RRS screw clamps will hold any of them. Markins lever release QR clamps can be adjusted to fit any of the plates but generally are adjusted to fit a specific brand plate, not a routinely recommended field adjustment. I do not know specifically if acratech and Kirk use the same dimensional tolerances (I use Kirk, RRS, Wimberley, and Markins stuff). Kirk and RRS are very friendly and very helpful if you give them a call. I have a RRS replacement foot for the Nikon 70-200 f/2.8 which attaches the same as original and is compatible with the clamp on ballhead. I think the kirk collar for the f/4 does not need an additional plate as the foot is the plate and should be Arca-Swiss compatible.
