I picked up this inexpensive spring mic a while back. There are some reviews that it's not calibrated, but mine was dead nuts when measured against a set of dial calipers. Worst case, buy a few until you get an accurate one and return the others.

This is an interesting way to measure installed height. If I'm reading it right, you put this in place of the spring and rotate the collar until the valve is seated and the collar cannot turn anymore. Let's say that at that point, you get a 1.910 number and the number you're aiming for is 1.890, you would just need a .020 shim to get the proper installed height.
